9月18事变心得体会 篇1

　　经过这学期软件工程实验的学习，深深感到用户需求对软件的重要性。成功的软件产品是建立在成功的需求基础之上的，而高质量的需求来源于用户与开发人员之间有效的沟通与合作。当用户有一个问题可以用计算机系统来解决，而开发人员开始帮助用户解决这个问题，沟通就开始了。

　　需求获取可能是最困难、最关键、最易出错及最需要沟通交流的活动。对需求的获取往往有错误的认识：用户知道需求是什么，我们所要做的就是和他们交谈从他们那里得到需求，只要问用户系统的目标特征，什么是要完成的，什么样的系统能适合商业需要就可以了，但是实际上需求获取并不是想象的这样简单，这条沟通之路布满了荆棘。首先需求获取要定义问题范围，系统的边界往往是很难明确的，用户不了解技术实现的细节，这样造成了系统目标的混淆。

　　其次是对问题的理解，用户对计算机系统的能力和限制缺乏了解，任何一个系统都会有很多的用户或者不同类型的用户，每个用户只知道自己需要的系统，而不知道系统的整体情况，他们不知道系统作为一个整体怎么样工作效率更好，也不太清楚那些工作可以交给软件完成，他们不清楚需求是什么，或者说如何以一种精确的方式来描述需求，他们需要开发人员的协助和指导，但是用户与开发人员之间的交流很容易出现障碍，忽略了那些被认为是"很明显"的信息。最后是需求的确认，因为需求的不稳定性往往随着时间的推移产生变动，使之难以确认。为了克服以上的问题，必须有组织的执行需求的获取活动。

　　需求获取活动要完成的任务或者步骤的过程如下：

　　编写项目视图和范围文档

　　系统的需求包括四个不同的层次：业务需求、用户需求和功能需求、非功能性需求。业务需求说明了提供给用户新系统的最初利益，反映了组织机构或用户对系统、产品高层次的目标要求，它们在项目视图与范围文档中予以说明。用户需求文档描述了用户使用产品必须要完成的任务，这在使用实例文档或方案脚本说明中予以说明。功能需求定义了开发人员必须实现的软件功能，使得用户能完成他们的任务，从而满足了业务需求。

　　非功能性需求是用户对系统良好运作提出的期望，包括了易用性、反应速度、容错性、健壮性等等质量属性。需求获取就是根据系统业务需求去获得系统用户需求，然后通过需求分析得到系统的功能需求和非功能需求。项目视图和范围文档就是从高层次上描述系统的业务需求，应该包括高层的产品业务目标，评估问题解决方案的商业和技术可行性，所有的使用实例和功能需求都必须遵从的标准。而范围文档定义了项目产品所包括的所有工作及产生产品所用的过程。项目相关人员对项目的目标和范围能达成共识，整个项目组都应该把注意力集中在项目目标和范围上。

September 18th incident experience Part 1

　　After this semester's software engineering lab, I am deeply impressed by the importance of user requirements for software. Successful software products are based on successful requirements, and high quality requirements come from effective communication and cooperation between users and developers. Communication begins when the user has a problem that can be solved with a computer system and the developer begins to help the user solve that problem.

　　Requirements acquisition is probably the most difficult, critical, error-prone and communication-intensive activity. Demand acquisition often have the wrong understanding: the user knows what the demand is, all we have to do is to talk to them to get the demand from them, as long as the user asked the system's target characteristics, what is to be accomplished, what kind of system can be suitable for business needs on it, but in fact, the demand acquisition is not imagined so simple, this road of communication is full of thorns. First of all, demand acquisition should define the scope of the problem, the boundaries of the system is often difficult to specify, the user does not understand the details of the technical implementation, which caused the confusion of the system's objectives.

　　Secondly, there is a lack of understanding of the problem. Users lack an understanding of the capabilities and limitations of a computer system, and there are many users or different types of users for any system. They don't know what the requirements are, or how to describe them in a precise way. They need assistance and guidance from the developers, but the communication between the users and the developers can easily be impeded, ignoring what is considered "obvious" information. Finally, requirements validation is difficult because of the volatility of requirements, which tend to change over time, making them difficult to validate. In order to overcome these problems, requirements acquisition activities must be carried out in an organized manner.

　　The process of tasks or steps to be accomplished by the requirements acquisition activity is as follows:

　　Prepare project view and scope documents

　　Requirements for a system include four different levels: business requirements, user requirements and functional requirements, and non-functional requirements. Business requirements describe the initial benefits of the new system to be provided to users, reflecting the high-level goal requirements of the organization or users for the system or product, and they are described in the project view and scope documents. The user requirements document describes the tasks that users must accomplish to use the product, which are described in the use case document or the solution script description. Functional Requirements define the software functionality that developers must implement to enable users to accomplish their tasks, thus satisfying a business need.

　　Non-functional requirements are the user's expectations for the good functioning of the system, including ease of use, responsiveness, fault tolerance, robustness and other quality attributes. Requirements acquisition is the process of obtaining user requirements based on the business requirements of the system, and then analyzing the requirements to get the functional and non-functional requirements of the system. The project view and scope document describes the business requirements of the system from a high level, which should include high-level product business objectives, assessment of the commercial and technical feasibility of the solution to the problem, and standards that all use cases and functional requirements must follow. The scope document, on the other hand, defines all the work included in the project product and the processes used to produce it. The entire project team should be focused on the project objectives and scope, which should be agreed upon by all project stakeholders.

　　从学习到现在，整整花了我好多的时间，真是苦啊，想想以前，刚开始学习时候，什么也不明白，看到自己的同学们个个都是高手，当时心中真是羡慕死了他们，之后。老师开始教我们了。

　　刚开始的时候总是觉得很新奇，总是觉得很喜欢似，一直到了好久，终于学完了，学了三维的，也学了建筑的，更是伤脑筋的，都是去学，在学校的时候，同学们总是觉得我学什么都很快，比他们学的好，但是我也觉得我其实没什么也好的，只是觉得自己比较花了多心思而以，学3D的时候，老师让我们考试了一次，真是没有想到，我考到了一差不多的成绩，以前我一直不敢相信自己，一直到了那次后，才发现自己其实真的学东西挺快的.，老师给我们画CAD图，老师发的是12张图纸，我知道很难，但是画起来的时候觉得也并没有什么，想不到我竟用一天的时间就搞定了，我的时学们有的觉得好像画了一天都没有搞定过一张，有的同学也画的很快，但是我知道在学校里的是第一个画完了的，一直到工作了，走进了社会，才发，原来外面的世界不是我想像的那样，外面的人，个个都是这行的高手，才知道我其实什么都不行，不过，我还算是很快的造就了我自己的工作，今天，我都不怕了，自己已经可以胜任这份工作了。

　　From learning to now, the whole spent a lot of my time, really bitter ah, think of the past, just started learning, what do not understand, see their classmates are masters, then the heart is really envious of them, after. The teacher began to teach us.

　　At the beginning of the time always feel very novel, always feel very like seem, has been to a long time, finally finished learning, learning three-dimensional, but also learn the building, but also the brain, are going to learn, in the school, the students always feel that I learn what is very fast, better than they learn, but I also think that I'm actually nothing good either, just feel that they are more spent more thought to learn 3D, the teacher let us take a test, really did not expect, I got a nearly the same grade. The teacher let us take a test, really did not think, I got a similar score, before I have not been able to believe themselves, has been to that time, only to realize that I actually really learn things quite fast. The teacher gave us to draw CAD drawings, the teacher issued 12 drawings, I know it's hard, but when I drew it up, I felt that there was nothing, I can't imagine that I actually used a day's time to get it done, and some of my classmates felt as if they had been drawing for a day and hadn't been able to get it done, some students drew very quickly, but I know that the first one to draw it up in the school was the first one to finish, and it was not until I had worked and walked into the society that I realized that the outside world was not what I thought it would be. The original outside world is not what I imagined, outside the people, all are masters of this line, only to realize that I actually can't do anything, but I am still very fast to create my own work, today, I am not afraid of it, I have been able to do the job.

　　提起安全，人们都知道它的重要性，但近来身边发生的一例人身伤亡事故却令人痛心，一个鲜活的生命刹那间化为乌有，给个人、家庭、企业带来巨大损失。通过学习《大唐甘谷发电厂5.13人身伤亡事故的通报》后，静下心来想一想，任何事故无外乎以下五种原因。

　　一是责任心：

　　有的'人由于养成不好的行为习惯，做事马虎大意，安排一项任务给他，没能尽职尽责，敷衍了事、随随便便，能应付交差了事，难免埋下安全隐患，危害不小。轻者质量下降，重者人命关天。

　　二是侥幸心理：

　　有的人出于图省事，怕麻烦，心想，这么简单的工作，干活时小心一点不就行了，不会出事的。然而，他们却忽略了一个重要方面：不按安全操作规程来，事故瞬间就会发生。

　　三是认识有限：

　　企业发展已有几十年，我们所使用的设备、设施都是新设备新技术，个人的知识、技术存在很大的局限性。由于种种局限性，导致了认识的差异，给安全生产埋下了许多隐患。

　　四是惰性：

　　谁都怕麻烦，想多一事不如少一事，工作不到位，简单地工作、不动脑筋的工作，忽略了许多环节，埋下了诸多安全隐患。

　　五是管理：

　　有时由于存在着干多干少、干好干坏一个样，滋养了部分懒惰的人。

　　以上五种原因就是安全事故的症结所在（排除为降低成本，置人命于不顾等情况）。所以，要解决安全问题，首先要解决人的思想、行为、习惯等问题，从认识上下功夫，充分调动人积极性，杜绝懒惰，才能保障人生安全。

　　Mention of safety, people know the importance of it, but recently around a case of personal injury and death accidents are heartbreaking, a living life into nothing in an instant, to individuals, families, enterprises to bring great losses. Through the study of "Datang Gangu Power Plant 5.13 personal injury and death accidents in the briefing", quietly think about any accident is no more than the following five reasons.

　　One is accountability:

　　Some 'people as a result of bad behavioral habits, sloppy and careless, arranged a task to him, failed to do his duty, perfunctory, casual, can cope with the work, inevitably buried hidden safety hazards, the harm is not small. Light quality decline, heavy lives are at stake.

　　The second is a fluke:

　　Some people, out of a desire to save trouble and fear of trouble, think that such a simple job, work a little more carefully not on the line, there will be no accident. However, they overlook an important aspect: if they don't follow safety procedures, accidents can happen in an instant.

　　Third, there is limited awareness:

　　Enterprises have been developed for decades, and the equipment and facilities we use are all new equipment and technology, and there are great limitations in personal knowledge and technology. Because of all the limitations, it leads to differences in understanding, which sows many hidden dangers to safety production.

　　Fourth, inertia:

　　Anyone who is afraid of trouble, wanting to do more is better than less, the work is not in place, simple work, no brain work, ignoring many links, buried many hidden dangers of safety.

　　Fifth, management:

　　Sometimes, due to the existence of more or less work, good work or bad work, it nourishes some of the lazy people.

　　The above five reasons are the crux of security accidents (excluding the case of putting human lives at risk in order to reduce costs, etc.). Therefore, in order to solve the security problem, we must first solve the problem of human thought, behavior, habits, etc., from the understanding of the work, fully mobilize people's enthusiasm, and put an end to laziness, in order to protect the safety of life.

　　本次创新实验是我参加的第二次院里的本科生实验项目，第一次是大三期间参加的开放实验项目，但这次是我第一次参与一个完整的创新实验过程，从最初的方案选取，到实验初步计划，到具体实验计划，再到实验的实施、结果分析，都需要我考虑周全，按部就班地进行。

　　最初确定实验方向，对于我来说难度不大，因为在项目申请前我已经经过了充分的文献调研以及与指导老师的讨论，确定要做印迹材料的研究这样一个课题。往往大方向的确定是容易的，而具体实施起来才会认识到层层困难。由于之前没有进行过配位印迹材料传感器的合成，因此必须查看大量文献资料，了解具体实验方法，结合我的具体目标，从而确定实验的步骤。而制定一项完整的计划，往往有许多考虑不周到的地方，例如在进行实验优化时漏掉一些影响因素，时间安排不合理等等。

　　实验的开展是整个项目最关键、耗时最长也是遇到困难最多的阶段。一开始就遇到了溶解度的问题，比如，在一些弱极性的溶剂中金属盐溶解度很差。在材料的合成阶段，有时对同一个条件重复合成两批材料，但是它们的效果差别却非常大，后来寻找原因时，在实验记录本发现原来这两批涂层合成时天气的湿度差别很大，天气的湿度对材料的合成影响很大。

　　在后期的实验数据处理、结果分析阶段，如何将具体的实验数据整理、分析，从中提炼出对我们的分析有用的数据，是对我分析、研究能力的考验。通过一年的实验、研究，我在创新能力、动手能力、组织能力以及专业知识等方面都有不同程度的收获，这为我以后的研究生工作积累了一定的基础。

　　This innovative experiment is the second undergraduate experimental project in the institute that I have participated in, the first one was an open experiment project during my junior year, but this is the first time I have participated in a complete innovative experimental process, which requires me to be well thought out and step-by-step, from the initial selection of the program, to the preliminary plan of the experiment, to the specific experimental plan, to the implementation of the experiment, and to the analysis of the results.

　　Initially determining the direction of the experiment was not too difficult for me because I had already gone through sufficient literature research and discussions with my advisor before applying for the project, and determined that I wanted to do a topic such as the study of imprinted materials. Often, the determination of the general direction is easy, and the concrete implementation will recognize the layers of difficulties. Since the synthesis of ligand-imprinted material sensors had not been carried out before, it was necessary to review a large amount of literature to understand the specific experimental methods and combine them with my specific goals, so as to determine the steps of the experiment. While making a complete plan, there are often many ill-considered aspects, such as omitting some influencing factors when performing experimental optimization, unreasonable time schedule and so on.

　　The conduct of the experiments was the most critical, time-consuming and difficult phase of the whole project. Solubility problems were encountered at the beginning, for example, the metal salts were poorly soluble in some weakly polarized solvents. At the stage of material synthesis, sometimes two batches of materials were synthesized repeatedly under the same conditions, but their results were very different. Later, when we searched for the reason, we found out in the experimental record book that the humidity of the weather during the synthesis of these two batches of coatings was very different, and the humidity of the weather had a great influence on the synthesis of the materials.

　　In the later stage of experimental data processing and result analysis, how to organize and analyze the specific experimental data, and extract the data useful for our analysis from them is a test of my analytical and research ability. Through one year's experiments and research, I have gained different degrees of innovative ability, hands-on ability, organizational ability and professional knowledge, which has accumulated a certain foundation for my future postgraduate work.

　　大二上学期第16周，在老师的指导下，我们班进行了为期一周的CAD制图集中实训。本次实训课题是绘制一级直齿圆柱齿轮减速器，这次实训不仅巩固了自己以往所学的知识，更加培养了自己的动手能力。

　　CAD实训的第一天，同学们兴奋地来到机房，打开电脑，在老师给我们介绍了实训内容和要求后，开始进行CAD操作。我也没有闲着，开机后打开CAD程序，迅速建好图层并保存。三张零件图，一张装配图，这是我们这一周的任务。虽然在实训前，我们已经学习了将近一个学期的CAD课程，但都是以简单的几何图形作为对象，现在画减速箱，看着图纸觉得蛮简单的，实际画起来还是不容易。 实训中图样的.简单绘制是难不倒我的，轴和齿轮我很快就完成了绘制。可是在标注时却遇到了麻烦。标注中表面结构符号中的可去除材料符号在标注中有没有这种符号的标注，自己一笔一划的绘制的话速度肯定又跟不上去。在进行直径标注时，我也总是做错，后来请教同学知道了我需要新建一个直径标注样式，并要在主单位中加直径的前缀，而且一定是要在英文编写状态下输入，在应用直径标注时要将其设置为置为当前。极限偏差我运用也不熟练，在和同学的商讨中，我知道了极限偏差的标注是要在“特性”里边设置调整的，当然也可以在标注设置里边“修改”、“偏差”进行设置。但是由于标注里边的是对整个标注进行设置的，由于每个尺寸的偏差会有不同，因此大多数人会选择在“特性”中修改。而且，在绘图中我发现要着重注意什么线应该用什么图层，比如结构线应用粗实线，中心线应用点化线，标注适合用细实线，不然很容易用错图层。

　　实训一周，在画箱座和最后的装配图时感到棘手。图形结构有些复杂，线很多，尺寸也很多。画箱座零件图时，偏移、移动、打断、延伸、旋转、修减等基本上所有的知识都要运用上很多次。装配图的拼装时，需要学会创建块和插入块，然后应用移动和旋转精准的将各个零件图拼装起来，这些都需要耐心和细心。

　　一周的CAD实训让我记忆深刻，使我学到了很多新知识，也让我更加熟练地掌握了CAD软件的应用，同时也让我们学会在学习生活中要戒骄戒躁、细心谨慎。很欣慰在这一周里收获了这么多！

　　In the 16th week of the first semester of the sophomore year, under the guidance of the teacher, our class carried out a one-week intensive practical training in CAD drawing. The subject of this practical training is to draw a first-class straight-toothed cylindrical gear reducer, this practical training not only consolidate their previous knowledge, but also develop their hands-on ability.

　　On the first day of CAD practical training, students excitedly came to the computer room, turned on the computer, after the teacher introduced us to the content and requirements of the practical training, began to CAD operation. I also did not idle, boot open the CAD program, quickly build a layer and save. Three parts drawings and one assembly drawing, this is our task this week. Although before the practical training, we have studied nearly a semester of CAD courses, but are simple geometric shapes as the object, and now draw the reduction gearbox, looking at the drawings feel quite simple, the actual drawing is still not easy. Practical training in the drawing of . Simple drawing is not difficult to defeat me, shafts and gears I quickly finished drawing. But in the labeling but encountered trouble. Removable material symbols in the surface structure symbols in the labeling symbols in the labeling there is no such symbols in the labeling, their own one-by-one drawing, then the speed certainly can not keep up. In the diameter of the labeling, I always do wrong, and then asked my classmates to know I need to create a new diameter labeling style, and to add the diameter of the main unit of the prefix, and must be in the state of the English writing input, in the application of the diameter of the labeling should be set to set to the current. I am not skilled in the use of limit deviation, in discussion with my classmates, I learned that the limit deviation of the labeling is to be adjusted in the "characteristics" settings, of course, you can also set the labeling settings in the "Modify", "Deviation It can also be set in "Modify" and "Deviation" in the labeling settings. However, since the setting in the labeling is for the whole labeling, due to the deviation of each size will be different, so most people will choose to modify in the "characteristics". Moreover, in drawing, I found that I should pay attention to what lines should be used in what layer, for example, the structure line should be thick solid line, the center line should be dotted line, and the annotation is suitable to use thin solid line, otherwise it is easy to use the wrong layer.

　　Practical training week was tricky when it came to drawing the box seat and the final assembly drawing. The structure of the drawings was somewhat complex, with lots of lines and dimensions. Offsets, moves, breaks, extensions, rotations, trims and subtractions, basically everything, had to be applied many times when drawing the box seat parts drawing. When assembling assembly drawings, you need to learn to create blocks and insert blocks, and then apply moves and rotations to accurately put the individual part drawings together, all of which requires patience and care.

　　A week of CAD practical training let me remember, so that I learned a lot of new knowledge, but also let me more skillful grasp of the application of CAD software, but also let us learn to learn in the study of life to guard against arrogance, careful and prudent. I am very glad to have gained so much in this week!

　　10月10日，在督导室黄老师的指导下，自行阅读学习了学院的《教学事故认定及处理暂行办法》文件。

　　此文件内容全部针对教学岗位容易出现问题的地方进行了规定和约束，是教学过程正常进行的保障基础。通过学习，知道了学校对于各项教学事故的认定，以及处罚细则，总体感觉对教师和教学管理工作者都很严格。

　　通过对文件的学习，了解到了作为一名教师在日常工作中，应该遵循的原则和教学相关工作的底限，也算是教师工作的准则之一了。文件中把教学事故分为三个档次：一般教学事故、严重教学事故、重大教学事故，其中，一般教学事故中有些内容可能平时没太重视，也不知道，在学习了该文件以后就要引起重视了，比如出考题难易程度的把控上要多花点功夫。

　　文件对各项事件违反后都做出了的`明确处罚，除了一般教学事故仅扣除一定金额的奖金津贴外，严重教学事故和重大教学事故都会影响到自己的评级评优、晋级等，情节严重者，还要影响整个教师的职业生涯。

　　虽然文件列明的事项很多，但我觉得，作为一名教师，应该自觉做到不违反文件上的任何条例，并且只要自己用心、努力，就能做到不产生任何教学事故。

　　学习了这个文件也是给我打了预防针，尽管我的教师职业生涯才开始，但我一定争取在整个职业生涯都不产生任何教学事故。

　　On October 10, under the guidance of Mr. Huang from the Supervision Office, we read and studied on our own the document "Interim Measures for Determination and Handling of Teaching Accidents" of the college.

　　The contents of this document are all aimed at the teaching position where problems are prone to occur to provide regulations and constraints, which is the basis of the guarantee of the normal conduct of the teaching process. Through the study, I know the school for the identification of various teaching accidents, as well as punishment rules, the overall feeling of teachers and teaching management workers are very strict.

　　Through the study of the document, I have learned that as a teacher in the daily work, I should follow the principles and the bottom line of teaching-related work, which is also considered one of the guidelines for teachers' work. The document classifies teaching accidents into three grades: general teaching accidents, serious teaching accidents and major teaching accidents, in which some contents of the general teaching accidents may not be paid too much attention to in normal times, and do not know, but after studying the document, we have to pay attention to it, for example, we have to put more efforts in controlling the degree of difficulty of the examination questions.

　　The document provides clear penalties for all violations, except for general teaching accidents, for which only a certain amount of bonus and allowance is deducted, serious teaching accidents and major teaching accidents affect one's rating, promotion, etc., and, in serious cases, the entire teacher's career.

　　Although there are many matters set out in the document, I feel that, as a teacher, I should consciously do not violate any of the regulations set out in the document and that, with my own dedication and hard work, I will be able to do so without producing any teaching accidents.

　　Studying this document was also a shot in the arm for me to make sure that even though my career as a teacher has only just begun, I will strive to not produce any teaching accidents throughout my career.

　　时间过的很快，一转眼就到了CAD实训周结束的时候了，记得在实训的第一天，老师给我们将了这周实训的任务安排，讲述了本周实训的主要资料，实训目的以及好处所在，然后交代了一些细节方面的问题，强调应当注意的一些地方，以及考试成绩打分等。

　　虽然时刻很短很紧，但是我一向认认真真去绘制每一个图，思考每一个细节，作图步骤，哪怕是一个很小的问题。的确，在作图的过程中我遇到了不少的难题，但都在同学的帮忙下，一个个的被我解决，自己难免会感到有点高兴，从而增加了对CAD的浓厚兴趣。

　　说到它的使用性，坚信许多同学都有同感。我们从书上得知，CAD能够绘制机械、建筑、航空、石油等多方面的二维平面图形和三维立体图形等等，因此说它的使用性是十分之广泛的。我们在绘制图形的时候要注意线条的宽度，字体的美观。此刻用CAD就完全没有这方面的'问题，粗细线条全用“特性”来规范，一目了然。尺寸也相当准确，在命令提示行里输入多少就是多少，也不用拿着丁字尺在图纸上比画来比画去，到头来还是达不到十分准确。画线线连结、圆弧连接的时候CAD在尺寸方面的优势就更加明显，比如画圆与直线相切的时候，手工绘图只能凭感觉觉得差不多就画上去，每一条画得都不一样，怎样看都不对称。用CAD画，打开对象捕捉就能把切点给抓进来，又快又准！尺寸标注更是快捷，两个点一拉，左键一点就完成一个标注，不用画箭头，不用标文字，只要自己设计好标注格式，计算机就能按要求标出来。插入文字也很方便，在多行文本修改器里输入文字资料就能出来绝对标准的国标字，比起我们手写的字就美观漂亮的多！粗糙度、基准符号、标题栏等做成块就能够随意插入，用不着一个一个地画了，用起来确实很快！

　　尺寸标注是工程制图中的一项重要资料。在绘制图形是时，仅仅绘制好的图形还不能看什么来，也不足以传达足够的设计信息。只有把尺寸标住标在自己的图形上方，就会让看图者一目了然，CAD带给的尺寸标注功能能够表达物体的真实大小，确定相互位置关联使看图者能方便快捷地以必须格式建立贴合行业或项目标准的标注。CAD中的标注尺寸有线性尺寸、角度直径半径引线坐标中心标注以及利用Dim命令标注尺寸，在设置尺寸标注，尺寸标注实用命令，利用对话框修改尺寸对象标注形位公差以及快速标注只要弄懂了上方的各个标注你就能够字图形上标注各种尺寸。

　　最后，学习CAD的目的就是能够完成与之相关的实际绘制任务，在实际工作中能够更快更准的完成制图作业。本次的CAD实训就是运用前面所有的各种绘图工具与修改工具进行绘制的，期望透过这次的复习和巩固在加上以后的完善能够更灵活快速准确的绘制各种图形从而发挥出CAD的巨大作用！

　　这天是最后是CAD实训的最后一天。结合我自身对CAD的学习状况，我将继续练习使用CAD，做到能够把它运用得得心应手、挥洒自如，使它成为我今后学习和工作的好助手！

September 18th incident experience Part 8

　　Time passes quickly, a turn of the eye to the end of the CAD training week, I remember the first day of training, the teacher gave us will be the task of this week's training arrangements, the main information about this week's training, training purposes and benefits, and then explain some details of the problem, emphasize should pay attention to some of the places, as well as the examination results scoring and so on.

　　Although the time is very short and tight, but I have always been serious to draw every picture, think about every detail, drawing steps, even if it is a very small problem. Indeed, in the process of drawing I encountered a lot of difficult problems, but all in the help of my classmates, one by one, I solved, I will inevitably feel a little happy, thus increasing the strong interest in CAD.

　　Speaking of its usability, I firmly believe that many students have the same feeling. We know from the book, CAD can draw mechanical, architectural, aviation, petroleum and other aspects of the two-dimensional plane graphics and three-dimensional three-dimensional graphics and so on, so that its usability is very broad. We have to pay attention to the width of the lines when drawing graphics, font beautiful. At the moment with CAD there is no such 'problem, thick and thin lines all with "characteristics" to standardize, at a glance. Size is also quite accurate, in the command prompt line to enter how much is how much, and do not have to hold a ruler in the drawings than drawing to draw to, in the end, or not up to very accurate. Drawing line connection, arc connection when CAD in the size of the advantage is even more obvious, such as drawing a circle tangent to a straight line, hand-drawn can only feel almost on the drawing up, each drawn differently, how to look at the asymmetry. Drawing with CAD, open the object capture will be able to capture the tangent point in, fast and accurate! Size labeling is even faster, two points of a pull, left click on the completion of a labeling, do not have to draw arrows, do not have to mark the text, as long as their own design of the labeling format, the computer will be able to mark out according to the requirements. Insert text is also very convenient, in the multi-line text modifier to enter the text data will be able to come out of the absolute standard of the national standard word, compared to our handwritten words on the beautiful and beautiful! Roughness, datum symbols, title bars, etc. made into a block can be inserted at will, not to draw one by one, with a really fast!

　　Dimensioning is an important piece of information in engineering drawing. In the drawing of graphics is, just draw a good graphic can not see what comes, also not enough to convey enough design information. Only the size of the label to stay marked in their own graphics above, will allow the viewer to see at a glance, CAD to bring the size of the labeling function to express the true size of the object, to determine the location of each other associated so that the viewer can easily and quickly to must be formatted to establish the labeling to match the industry or project standards. CAD in the labeling of dimensions are linear dimensions, angle diameter radius lead coordinate center labeling and the use of Dim command labeling! Dimensions, in setting the size of the labeling, dimensioning utility commands, the use of dialog boxes to modify the size of the object labeling shape and location tolerances and fast labeling as long as you understand the above each labeling you will be able to label a variety of dimensions on the word graphics.

　　Finally, the purpose of learning CAD is to be able to complete the actual drawing tasks related to it, in the actual work can be faster and more accurate completion of the mapping operation. This CAD practical training is the use of all the previous various drawing tools and modification tools for drawing, expect through this review and consolidation in addition to future improvements can be more flexible, fast and accurate drawing of a variety of graphics so as to play a great role in CAD!

　　This is the last day of CAD practical training. Combined with my own learning of CAD, I will continue to practice the use of CAD, to be able to use it at ease, free of charge, so that it will become a good assistant for my future study and work!

9月18事变心得体会 篇9

　　在电力工作生产中，生产者实现“要我安全”到“我要安全”的观念转变，是安全思想由强制性到自觉性的一次质的飞跃。

　　但是，要确保电力工作生产安全，这一转变依然是不够的，还必须由“我要安全”转变到“我会安全”，才能够从事故源头上遏制不安全因素的作用，减少或避免事故的发生。

　　电力工作生产是一门非常复杂的系统工程，而生产安全又是这一系统工程中诸多因素综合作用的结果。一般而言，电力工作生产事故有三类：一是“天灾”，如雷电、大风、暴雨、施工爆破等不可控或不便控的自然因素，有其突发性。二是线路、设备、器材的“先天不足”，有其隐蔽性。三是“人祸”，人为地违法、违规、违章，有其盲目性。且占所有事故中的绝大部分。而“人祸”又可分为三种表现形式：其一是对规章明知故犯，明知这样做不符合要求，但图一时方便或抱着侥幸心理的习惯性违章。其二是对规章似懂非懂，知其一，不知其二，工作中又恰好在其二中发生了问题。其三是对规章不懂装懂，稀里糊涂，发生了事故才”恍然大悟或恍然半悟。

　　显而易见，工作人既是事故的制造者又是事故的受害者。但是，可以肯定地说，所有事故的发生都不是工作人的主观愿望。因此，“我要安全”也就仅仅是一种良好的主观愿望，要真正取得确保电力工作生产安全这一客观效果，就必须解决好“我会安全”这一根本。

　　大凡发生了事故后，总结时都不难得出：“安全基础不牢，安全观念淡薄，安全管理不善，技术素质不高，安全防护能力弱，习惯性违章”等诸多教训的结论，都会把违章作业认为是事故的“病灶”，也提上了人们的议事日程。但深层次地去分析违章作业存在的原因，拿出切实可行的从源头上杜绝违章作业的办法来，是不是真正摆上了我们各级安全部门、管理者、生产人的办事日程？

　　勿庸置疑，经过有电以来的生产实践和血的教训，总结提炼了一套有效确保电力工作生产安全的规章制度。各电力工作生产企业又结合实际根据不同生产时期制定了大量的具体保证措施，以及上级随机性，针对性的电力工作安全生产的指示、通报、要求等。这些是确保电力工作生产安全的依据，且有唯一性。但是电力工作生产是一个错综复杂，千变万化的过程，从事生产的人又是这个过程是否安全的决定因素。而人的认识水平，接收能力，工作姿态，经验积累等等又各尽不同，要把所有确保电力工作生产的依据变为每一个从事电力工作生产的职工的自觉行动，解决好“我会安全”的问题，应是从事电力工作生产安全的管理者，生产者长期的`，艰巨的，复杂的课题。笔者认为：唯一的途径就是学习--学习--再学习。

　　首先，要为我而学。安全既是电力工作生产本身的需要，更是从事生产职工的生存需要，安规技规既反应了电力工作生产安全的客观规律，又是从事生产人的行为规范。因此，每一个从事电力工作生产的人，都应明白学习安全技能，既是企业的需要，更是自我的需要。这就需要“教条主义”、“本本主义”而不要“实用主义”、“形式主义”。把强制性与自觉性有机地结合起来不断学习，反复学习。从个体到团队都形成一个良好的学习安全技能的良好氛围。并制定配套的学习激励机制和考核办法，点滴学习，日积月累，这样不仅能够对安规、技规等安全生产的内涵有了深刻的理解，就能在生产过程中运用自如。也只有人人成为安全明白人，才能事事做到安全人。

　　第二，要因人施训。近些年来，职工队伍生产技能、安全防护能力差，人才断层等已达成了管理者的共识。把加强教育培训也作为解决上述问题的有力措施。但各级抓各级的事，一级抓一级，一级向一级负责，真正形成有效的教育培训链还是力度不够。往往形成上级制定安全措施“一字一字地抠”，经逐级折扣后贯彻到生产中却“一把一把地丢”。因此要把从事电力工作生产的各类人员分门别类，拉开梯次，有的放矢地逐级制定年度、月度培训计划，以“蚂蚁啃骨头”的精神，专人负责。充分利用班组站法定的每周一次安全学习和每天班前会进行。这样每周解决一个难题消除一个不安全隐患，一年就能解决５２个“会”和消除５２个不安全隐患。每天学习一条技规、安规，一年就能学懂弄通２００多条。持之以恒地坚持下去，耳濡目染地强化人的意识，就能潜移默化地在职工队伍中形成一道事故的防线。

　　第三，要善于纠偏，电力工作生产暴露问题和存在潜在的不安全因素是正常的，关键是要正视问题和善于做到“见于未萌，禁于未发”。有效的办法就是边生产边整顿，发生问题及时整，安全顺利定期整。明白“磨刀不误砍柴工”和“温习规程与包扎’伤口”’一样重要的深刻道理。自己发生了事故多从自我找原因，不要“摔了跤总怪路不平”。把别人的事故当着自己的教训来接受；把小问题当着大问题来解决；把带有倾向性和危害性的现象消灭在萌芽状态。从真正意义上体现“安全第一，预防为主”的根本方针。

　　“要我安全”到“我要安全”的转变需要漫长的过程，而“我要安全”到“我会安全”更需一个漫长而渐进的过程，甚至说是一个无终极的课题。笔者提出以上粗浅认识和解决途径还远远不能解决“我会安全”的问题。此文主要是基于安全生产观念上的一次完善和“抛砖引玉”，其目的是引发从事电力工作生产的职工围绕“我会安全”进行深层次的思考和探索。

September 18th incident experience Part 9

　　In the production of electric power work, producers to realize the "I want to safety" to "I want to safety" conceptual change, is the safety of thought from mandatory to consciously a qualitative leap.

　　However, to ensure the production safety of electric power work, this change is still not enough, but also by "I want safety" to "I will be safe", in order to be able to curb the role of insecurity from the source of accidents, reduce or avoid the occurrence of accidents.

　　Power work production is a very complex systems engineering, and production safety is the result of the combined effect of many factors in this systems engineering. Generally speaking, electric power production accidents have three categories: First, "natural disasters", such as lightning, wind, rainstorms, construction blasting and other uncontrollable or inconvenient control of natural factors, its suddenness. The second is the line, equipment, equipment, "congenital defects", has its hidden. The third is "man-made disasters", man-made illegal, illegal, against the rules, has its blindness. And account for the vast majority of all accidents. And "man-made disasters" can be divided into three manifestations: one is the regulations knowingly, know that this does not meet the requirements, but the convenience of the moment or hold a fluke habitual violation. The second is the regulations seem to understand, know one, do not know the second, the work happens to be in the second problem. Third, the regulations do not pretend to understand, confused, accidents occur only "suddenly realized or suddenly half realized.

　　It is obvious that the workman is both the creator and the victim of accidents. However, it can be said with certainty that the occurrence of all accidents is not the subjective desire of the workman. Therefore, "I want to safety" is only a good subjective desire, to really ensure that the objective effect of the production safety of electric power work, it is necessary to solve the "I will be safe" this fundamental.

　　Where accidents occur, it is not difficult to summarize: "security foundation is not solid, the concept of safety is weak, poor safety management, technical quality is not high, weak safety protection, habitual violation of the rules," and many other lessons of the conclusion, will be considered to violate the operation of the accident "foci! ", also on people's agenda. But the deep level to analyze the reasons for the existence of unauthorized operation, come up with practical ways to eliminate unauthorized operation from the source, is not really on our security departments at all levels, managers, producers of the agenda?

　　Needless to say, after having electricity since the production practice and blood lessons, summarized and refined a set of effective to ensure the production of electric power work safety rules and regulations. Each electric power work production enterprise and combined with the actual according to different production period formulated a large number of specific guarantee measures, as well as the superior random, targeted electric power work safety production instructions, circulars, requirements and so on. These are the basis for ensuring the safety of electric power work production, and have the uniqueness. But the power work production is an intricate and complex, ever-changing process, engaged in the production of people is the process of whether the safety of the determining factors. And people's level of understanding, the ability to receive, work posture, experience accumulation and so on are different, to ensure that all the basis for the production of electric power work into each engaged in the production of electric power work of the staff's conscious action, to solve the problem of "I will be safe" should be engaged in the production of electric power production safety managers, producers of long-term `, the difficult, complex subject. Arduous, complex subject. The author believes: the only way is to learn - learn - learn again.

　　First of all, to learn for me. Safety is not only the need for power production itself, but also engaged in the survival of production workers need, safety regulations and technical regulations both react to the objective law of power production safety, but also engaged in the production of people's behavioral norms. Therefore, every person engaged in the production of electric power work, should understand that learning safety skills, both the needs of the enterprise, but also the needs of the self. This requires "dogmatism", "book" and not "pragmatism", "formalism". The mandatory and conscientious organic combination of continuous learning, repeated learning. From the individual to the team to form a good learning safety skills of a good atmosphere. And the development of supporting learning incentives and assessment methods, bit by bit learning, day by day, so that not only can the safety regulations, technical regulations and other connotations of production safety have a deep understanding, can be used freely in the production process. Only when everyone becomes a safe and understandable person, can we do everything safely.

　　Secondly, training should be tailored to the individual. In recent years, the workforce has reached a consensus among managers on the poor production skills, safety and protection capabilities, and the talent gap. Strengthening education and training is also a powerful measure to solve the above problems. However, all levels of things at all levels, one level to one level, one level to one level of responsibility, the real formation of an effective education and training chain is still not strong enough. Often the formation of the upper level of the development of security measures, "word by word to key", after the level by level discounts carried out to the production of a "handful of a handful of lost". Therefore, to engage in the production of electric power work of all types of personnel in different categories, pull open the ladder, targeted level by level to develop annual and monthly training programs to "ants gnawing bones" spirit, a person in charge. Make full use of the weekly safety study and daily pre-shift meeting of the statutory group station. This week to solve a problem to eliminate a hidden danger of insecurity, a year will be able to solve 52 "will" and eliminate 52 hidden danger of insecurity. Every day to learn a technical regulations, safety regulations, a year will be able to learn to understand more than 200. Persistently adhere to, and strengthen the awareness of people, can be subtle in the workforce to form a line of defense against accidents.

　　Third, to be good at correcting, electric power work production problems and the existence of potential insecurity is normal, the key is to face up to the problem and good to do "see in the bud, forbidden in the unissued". Effective way is to rectify the production side, the occurrence of problems in a timely manner, safe and smooth regular whole. Understand that "sharpening the knife is not a mistake" and "review procedures and bandage 'wounds' 'as important as the profound truth. Accidents occur more from the self to find the reason, do not "fall always blame the road is not flat". Take other people's accidents as their own lessons to accept; small problems as big problems to solve; with tendency and harmful phenomena nipped in the bud. From the real sense of "safety first, prevention-oriented" fundamental policy.

　　The transformation from "want me to be safe" to "I want to be safe" requires a long process, while "I want to be safe" to "I will be safe! "More need a long and gradual process, or even said to be a non-ultimate subject. The author puts forward the above shallow understanding and solution is far from being able to solve the problem of "I will be safe". This article is mainly based on the concept of production safety on a perfect and "throw a brick to attract jade", its purpose is to trigger the production of workers engaged in electric power work around the "I will be safe" to carry out in-depth thinking and exploration.

　　Profoundly analyze and reflect on the shortcomings of the work. First, the requirements for themselves are not high enough. Second, the safety knowledge is not rich enough. Third, the service consciousness still needs to be improved. Mainly reflected in the individual time requirements of more, criticize the strict, and guide the grass-roots work to help the number of times less, not in-depth. Fourth, the degree of innovation in work methods is insufficient.

　　Develop a plan to improve self-efficacy in a practical way.

　　Change consciousness, enhance service. Effective change of consciousness, down the mine inspection not only as long as to find the problem, check the hidden danger, but also on-site guidance for rectification, for the problem, hidden danger rectification of ideas, want to hair method, seek countermeasures, and constantly strengthen the grass-roots units to help the work of the number of times, so as to continue to enhance the sense of service.

　　Broaden ideas and strengthen innovation. Actively communicate with leaders and colleagues, constantly summarize and improve, broaden ideas, innovative work methods, to ensure the efficient completion of the work.

9月18事变心得体会 篇11

　　时间就如那流淌着的河水，这个学期晃悠悠就流到了尽头。在本学期的教学中，我担任了11级电商班、11级直升班、11室内设计和12室内设计班的CAD教学工作，教学任务随着时光的流逝不断前行，在时间的声音里悄然完成。

　　一、从教学出发，审视自我

　　回顾我的教学工作，不知不觉中也有了五年的时间。岁月是一把杀猪刀，我们在岁月的流逝里逐渐衰老，教学经验却在逐年累积，面对的学生也在逐年变化，而我们要在这变化中不断改变策略，迎接新的使命。对于五年的时间，是一个说不得的时间，人生能有几个五年，究其教学工作及教学经验来说，总是在不断的自省，不断的去反问，不断的改进。

　　在我生命中的光阴耗去了，但甘苦点滴何在?随着教学工作的不断累积，作为教师的成绩感却越来越少，面对学生的教学管理如何进行，我们到底应该以怎样的姿态去面对自己今后可能无法绕开的这份工作?同时，在上课过程中，学生的差异明显，其间差距很大，花费了精力，但收效让人寒心，不断有优秀的学生离我而去，留下来的却老是让人伤肝动气。付出与获得轻重两欹，既让学生没有信心，也让我问心有愧。症结何在?怨怒学生笨没有用，找客观原因也没有用，对教育环境发牢骚是更不抵用。

　　二、从学情出发，以学生为主体

　　我们接触的学生是初中阶段成绩较差的群体，他们具有一下特点：

　　1、学生学习基础薄弱。大部分技校生是当前应试教育的牺牲品，初中阶段他们学习不好，升学无望，游离于学校和老师的关注之外，进而学业加剧荒废。许多学生，错别字频频出现，有的学生课文读不下来，新的知识掌握不了，给继续学习带来严重障碍。

　　2、心理问题多。通过对许多学生的.调查研究，发现大部分学生的家庭存在问题，有的学生家庭遭遇不幸，有的学生父母离异，有的学生是单亲家庭，自幼养成倔强、孤僻的性格，爱走极端。

　　3、学生学习的功利性强。技校生的学习目的很明确：希望能够摒弃文化知识基础差的硬伤，在技校学好一种或数种技能而立足社会。

　　4、学生学习缺乏主动性。许多技校生在初中时就是“不受欢迎的人”，对学习没一点兴趣，长期遭受老师和同学的歧视，内心极度自卑。

　　5、学生没有学习压力。学生来到技校从初中阶段的应试教育解放出来，没有了应试教育的压力，学习的压力也没有了。

　　三、从教学出发，改善教学方法，引导学生学习

　　对于教学，我认为需要引起学生学习兴趣，激发学生学习动机，在"想学"的基础上展开教学。

　　1、指明学生所要达到的目标和所学的内容，让学生知道学什么和学到什么程度.学生只有知道自己学什么和学到什么程度，才会有意识地主动参与。采用学生易于理解的方式.根据学生的不同特点，采用不同的教学方法，引导学生理解与年龄相符的知识。有效教学的核心问题是教学的效益，即是要在教学中寻找一种方式使得教师"少教"，而学生"多学"。

　　2、如何优化课堂结构进行有效教学?我觉得要完成教学任务，态度认真并代表学习的收获。扎实才有效，有效才扎实。不能用多媒体代替学生的想象，要有效地运用课外资源解决重难点。在解决问题上，需要以启发式方法提出问题但教师缺少等待，提出问题后很快就以暗示性的语言迅速地把思路和解决问题的方法引导到预先设计好的标准化的路线上来.最后学生在教师的牵引下把思维指向标准答案。

　　没能超越教材，没能作到在课堂上遇到突发事件要准备好，保持镇定，随机应变，从容面对的教学机智，以及克服困难需要的耐心，恒心，意志力和执着精神，教师游离于学生思考和生生互动以外。

　　四、从自我出发，不断提升完善自我

　　对于教学来说仅仅就用一本课本给学生上课是绝对不够的，要不断结合学生实际，更新教学观点，发展新的教学思路。

　　1.认真钻研，大胆求索

　　要改革，就要认真学习，掌握丰富的教育教学理论。有了理论，就可探索新的教学路子。“做到老，学到老”。学，就会有进取，就会有创新。因此，认真钻研教材，研究新编教材的目的意义。

　　2.勇于实践，做好榜样

　　把探索到的教学理论，付上于教学的实践中去。在实践中，做好理论付诸实践，努力寻求"自主"的出路。在公开课后，学校组织教师教研组内集体讨论﹑指出﹑更正。这样，就形成了人人都参与实践的探索研究的新局面，有力地推动了教学工作。

　　3.认真拓展，丰富知识

　　我利用业余的时间，到网上收集了一些和专业课程相关的教材和案例，作为我教学的后盾。备课就综合所搜集的知识，融会贯通之后，根据学生的实际情况把知识进行简化，让知识更通俗易懂，更容易让学生接受。

　　总之，在教学中我积极参与听课、评课，虚心向同行学习教学方法，博采众长，提高教学水平。不断自己教学反思，从中陈述一下自己的教学感悟和心得，吸收好的教学经验，在工作中一步一步前进，一点一滴成长。我们在教学中所需要前进的道路还很长，我们正在前行的道路上不断摸索而行。

September 18th incident experience Part 11

　　Time is like the flowing river, this semester wobbles to the end. In this semester's teaching, I took charge of the CAD teaching work of the 11th grade e-commerce class, the 11th grade helicopter class, the 11th interior design and the 12th interior design class, and the teaching task kept moving forward with the passage of time, and was quietly completed in the sound of time.

　　I. Examining the self in terms of teaching and learning

　　Looking back on my teaching work, I don't realize that it has been five years. Years is a killing knife, we in the passage of years gradually aging, teaching experience but the accumulation of years, the face of the students are also changing year by year, and we have to change in this change in the strategy to meet the new mission. For five years, is a time to say no, life can have a few five years, the study of its teaching work and teaching experience, always in the constant introspection, constantly to ask questions, and constantly improve.

　　The time in my life has been spent, but where are the sweet and bitter moments? With the accumulation of teaching work, as a teacher's sense of achievement is less and less, in the face of how to manage the teaching of students, how should we face their future may not be able to get around this work in the posture? At the same time, in the course of the lesson, the difference of the students is obvious, the gap between them is very big, spent energy, but the results are chilling, there are constantly excellent students left me, but those who stayed always make people hurt their liver and anger. The difference between what I give and what I get is so great that it gives the students no confidence and it gives me a guilty conscience. What's the problem? It's no use blaming the students for being stupid, it's no use looking for objective reasons, and it's no use complaining about the educational environment.

　　Second, from the learning situation, the student as the main body

　　The students we work with are a low-achieving group at the middle school level who are characterized by the following:

　　1. Students have a weak learning foundation. Most of the technical school students are the victims of the current exam-oriented education, junior high school stage, they do not learn well, there is no hope for further education, away from the school and teachers outside of the attention, and then increased abandonment of their studies. Many students, misspelled words frequently, some students can not read down the text, new knowledge can not master, to continue learning to bring serious obstacles.

　　2. There are many psychological problems. Through many students . Investigation and research, found that most of the students' families have problems, some students' families suffered misfortunes, some students' parents are divorced, and some students are single-parent families, which have developed stubborn and withdrawn character since childhood, and love to go to extremes.

　　3. Students' learning is highly utilitarian. The purpose of learning for technical school students is very clear: they hope to be able to abandon the poor cultural knowledge base of the hard, in technical schools to learn one or more skills and based on society.

　　4. Students' lack of initiative in learning. Many technical school students are "unpopular people" in junior high school, have no interest in learning, and suffer from long-term discrimination by teachers and classmates, with extremely low self-esteem.

　　5. Students have no pressure to study. Students come to technical schools to be liberated from the test-based education at the junior high school level, and there is no pressure to study without the pressure of test-based education.

　　III. Improving teaching methods and guiding students from teaching to learning

　　For teaching, I think we need to arouse students' interest in learning, stimulate their motivation to learn, and start teaching on the basis of "wanting to learn".

　　1. Specify the objectives to be achieved by the students and what they have learned, so that they know what they are learning and to what extent. Only when students know what they are learning and to what extent will they consciously and actively participate. Adopting methods that are easy for students to understand. Different teaching methods are used to guide students to understand age-appropriate knowledge according to their different characteristics. The core issue of effective teaching is the efficiency of teaching, that is, to find a way to make teachers "teach less" and students "learn more".

　　2、How to optimize the classroom structure for effective teaching? I think to fulfill the teaching task, the attitude is serious and represents the learning gain. Solid to be effective, effective to be solid. Can not use multimedia instead of students' imagination, to effectively use resources outside the classroom to solve the key problems. In problem solving, the need for heuristic methods to raise the issue but the teacher lacks wait, raise the issue soon after the suggestive language to quickly lead the ideas and problem-solving methods to the pre-designed standardized routes. Finally the students are pulled by the teacher to point their thinking to the standardized answer.

　　Failure to go beyond the textbook, failed to be prepared for emergencies in the classroom, to remain calm, improvise, calmly face the teaching resourcefulness, as well as to overcome the difficulties of the need for patience, perseverance, willpower and perseverance, the teacher is outside the students' thinking and student-student interaction.

　　Fourth, from the self, constantly improve and perfect themselves

　　It is absolutely not enough for teaching to use a textbook to give lessons to students, but to constantly combine with the actual situation of the students, update the teaching point of view, and develop new teaching ideas.

　　1. Study carefully and seek boldly

　　In order to reform, we must study carefully and master the rich theories of education and teaching. With theories, new ways of teaching can be explored. "Do old, learn old." When you learn, you will be enterprising and innovative. Therefore, it is important to study the textbooks carefully and examine the purpose and significance of the new textbooks.

　　2. Practice and be a good role model

　　Putting the theories of teaching and learning into practice. In practice, do a good job of putting theory into practice, and strive to find "independent" way out. After the open class, the school organized teachers to discuss collectively in the teaching and research group, pointed out, corrected. In this way, the formation of everyone involved in the practice of exploration and research of the new situation, a strong impetus to the work of teaching.

　　3. Seriously expanding and enriching knowledge

　　I use my spare time to collect some teaching materials and cases related to my specialized courses on the Internet as the backing of my teaching. The preparation of the lesson will synthesize the collected knowledge, and after integrating them, simplify the knowledge according to the actual situation of the students, so as to make the knowledge more understandable and easier for the students to accept.

　　In short, in teaching I actively participate in listening to classes, class evaluation, learning from peers teaching methods, learn from the best, improve the level of teaching. Continuously reflect on their own teaching, from which to state their own teaching perception and insights, absorbing good teaching experience, step by step in the work of advancing, bit by bit growth.

　　火与我们的生活息息相连，它无私的带给我们必不可少的光明和热量，但是，如果我们对火缺少警惕，调皮的火苗不断的扩散，以至于吞噬人的生命，俗话说：“水火无情、火善用之则为福，不善用之则为祸。”这一点也没错，有多少例子可以证明，火灾大多是在不经意间就发生了，比如丢一个烟头，就会引发一场火灾。

　　为了提高我们对发生火灾的应对能力，我们全体科室成员在护士长的带领下进行了一次关于火灾的应急演练。在演练过程中，我们每个人分工明确，清楚各自的职责，有序的`完成了管辖区病患的疏散逃生。在这次演练中自身也学到了很多，当发生火灾时，我们要保持镇定，清晰的头脑，火势可控时直接用灭火器扑灭火源。

　　火势不可控时，发现者通知主班护士拨打报警电话，然后启动消火栓，转运病人及贵重仪器等，在这过程中，更加明白了打消防电话也是不少的学问，消火栓的使用方法和各班的职责。同时，通过这次演练也更加强了我们对预防火灾及应对火灾的意识，对病人的安全指导方面也加强了宣教。“隐患险于明火，防范胜于救灾，责任重于泰山”在平时，我们做好预防工作，宣告安全知识，让大家都有这种意识，为我们的工作、生活盖上一层坚硬的保护罩，让我们的生命更快乐，更幸福，更美好！

　　Fire is closely linked to our lives, it selflessly brings us essential light and heat, but if we lack vigilance against fire, the mischievous embers continue to spread to the point of devouring human life, as the saying goes, "Water and fire have no mercy, fire is a blessing when it is used well, and a curse when it is not." This is also true, how many examples can prove that the fire is mostly inadvertently occurred, such as throwing a cigarette butt, will start a fire.

　　In order to improve our ability to respond to a fire, all of us in the department, led by the head nurse, conducted an emergency drill on fire. During the drill, each of us divided the work clearly, knew our respective responsibilities, and completed the evacuation of patients in our jurisdiction in an orderly manner. We also learned a lot from this drill, when there is a fire, we have to keep calm, clear mind, and when the fire is controllable, we should use the fire extinguisher to extinguish the fire directly.

　　When the fire is uncontrollable, the discoverer notifies the nurse in charge to call the police, then starts the fire hydrant and transfers the patients and valuable instruments, etc. In the process, we have better understood that there is quite a lot of learning to make a fire call, how to use the fire hydrant and the duties of each class. At the same time, through this drill, we also strengthened our awareness of fire prevention and response to fire, and strengthened the guidance for patient safety. "Hidden danger is more dangerous than open fire, prevention is better than disaster relief, and responsibility is heavier than Mount Tai" In normal times, we do a good job of prevention, proclaiming the knowledge of safety, so that we all have this kind of awareness, and put a hard protective cover on our work and life, so that our life will be happier, happier, and better!

　　随着计算机技术的飞速发展，计算机CAD技术已经深入到机械工程中，我们可以利用CAD技术设计图纸，用CAD 强大的辅助图形设计和三维实体造型功能改变传统的绘图方式，使我们化工类的学生既能摆脱传统机械制图学习的抽象和

　　枯燥，又能使我们的绘图学习变得更轻松而高效，并且更能适应现在社会对技术性人员的需求。

　　学习了AutoCAD这门课程，我对我们的专业又有了更深的了解，CAD是我们专业所必学的一个软件，这个软件不仅广泛用于工程、工业制图中的建筑工程、装饰设计、环境艺术设计、水电工程、土木施工等等。 精密零件、模具、设备等。还广泛应用于土木建筑、装饰装潢、城市规划、园林设计、电子电路、机械设计、服装鞋帽、航空航天、轻工化工等诸多领域。AutoCAD是由美Autodesk公司开发的通用计算机辅助设计软件，具有易于掌握、使用方便、体系结构开放等优点，能够绘制二维图形与三维图形、标注尺寸、渲染图形以及打印输出图纸，在化工行业中有着重要的.应用， AutoCAD是当前最流行的计算机辅助设计软件之一，具有强大的绘图功能。一方面，机械制图是AutoCAD的基础。比如设计图纸、设计流程。另一方面，AutoCAD是促进制图教学的有效工具。它取代了手工制图方法，利用其强大的绘图功能和编辑修改功能，可以快速、准确、美观地表达出所要画的机械图样，极大地提高了绘图效率和绘图质量。除了应用于化工行业之外，甚至被广泛应用于机械、建筑、电子、航天、造船、石油化工、土木工程、冶金、地质、气象、纺织、轻工、商业等诸多领域。

　　学习了CAD制图，我也总结了自己的一些学习经验和方法：首先，我认为基础很重要，学习CAD，需要一定的画法几何的知识和能力，需要一定的识图能力，尤其是几何作图的能力，所以，我认为学好《化工制图》是基础，《化工制图》学的好的学生CAD制图学起来会轻松容易的多。所以要想学好CAD，一定要打好基础。其次，基础不是很好的学生也不要放弃，循序渐进，不气不馁，多花点时间，使自己能由浅到深，一步一步来，由简到繁的掌握CAD的基础、技巧和方法；再次，学习的知识要学以致用，这会使自己有很大的进步，不要把主要精力花在各个命令孤立地学习上，要把学以致用的原则贯穿整个学习过程，从而使自己对绘图命令又深刻和形象的理解，这有利于培养自己独立绘图的能力。学习是重要的，但也不能死学，在理解的基础上掌握其绘图技巧也是很重要的，要学会比较容易混淆的命令，严格要求自己规范作图，养成良好的习惯。

　　实践证明，将机械制图与AutoCAD两门课程有机地结合起来，内容上既能避免了重复，又能很好地激发学生的学习兴趣，有效地减轻学生的学习负担。不以规矩不成方圆，工程标

　　注是零件制造、工程施工和零部件装配时的重要依据。在任何时候一幅工程图中，工程标注是不可少的重要部分。在某些情况下，工程标注甚至比图形还重要。只有以一定的标准严格要求自己，规范自己，不怕麻烦，真的做到用心去画好每一个图，在有一定时间进行强化记忆和安排学习，勤学多练，理论联系实际，并融会贯通—些画图的技巧，制作CAD图也就能够清晰、准确、高效。我相信，CAD一定可以学的最好。

　　With the rapid development of computer technology, computer CAD technology has been deeply into mechanical engineering, we can use CAD technology to design drawings, with CAD powerful auxiliary graphic design and three-dimensional solid modeling functions to change the traditional drawing, so that our chemical students can get rid of both the traditional mechanical drawing study of abstract and

　　It's boring, but it also makes our drawing studies easier and more efficient, and it's more responsive to the needs of today's society for skilled people.

　　Learned AutoCAD this course, I have a deeper understanding of our profession, CAD is our profession must learn a software, this software is not only widely used in engineering, industrial drawing in the architectural engineering, decorative design, environmental art design, water and electricity engineering, civil construction and so on. Precision parts, molds, equipment and so on. Also widely used in civil construction, decoration, urban planning, landscape design, electronic circuits, mechanical design, clothing, shoes and hats, aerospace, light industry, chemical industry and many other fields. AutoCAD is a general-purpose computer-aided design software developed by the U.S. Autodesk, Inc. with easy to grasp, easy to use, open architecture, etc., the advantages of being able to draw two-dimensional graphics and three-dimensional graphics, marking Size, rendering graphics and printouts, in the chemical industry has an important. Application, AutoCAD is currently one of the most popular computer-aided design software, with powerful drawing functions. On the one hand, mechanical drawing is the basis of AutoCAD. For example, design drawings, design process. On the other hand, AutoCAD is an effective tool to promote the teaching of drafting. It replaces the manual drawing method, and by using its powerful drawing function and editing and modification function, it can express the mechanical drawing to be drawn quickly, accurately and beautifully, which greatly improves the drawing efficiency and drawing quality. In addition to the chemical industry, it is even widely used in machinery, construction, electronics, aerospace, shipbuilding, petrochemical, civil engineering, metallurgy, geology, meteorology, textile, light industry, commerce and many other fields.

　　Learning CAD drawing, I also summarized some of my own learning experience and methods: First of all, I think the foundation is very important, learning CAD, need a certain knowledge and ability to draw geometry, the need for a certain degree of literacy, especially the ability to geometric drawings, so I think that learning chemical drawing is the basis of the "chemical drawing", "Chemical Drawing" to learn a good student CAD drawing will be easy to learn much easier. So in order to learn CAD, we must lay a good foundation. Secondly, the foundation is not very good students do not give up, step by step, not angry, not discouraged, spend more time, so that they can be shallow to deep, step by step, from simple to complex to master the basis of CAD, skills and methods; again, learning knowledge to learn to use, which will enable them to have a great deal of progress, do not spend the main energy in the isolation of individual commands on the study, to be used throughout the entire learning process, so that their understanding of drafting commands, and so that they have a good understanding of the drawing commands. Do not spend your energy on learning each command in isolation, but put the principle of learning by using throughout the whole learning process, so that you have a deep and graphic understanding of the drawing commands, which is conducive to the cultivation of their independent drawing ability. Learning is important, but can not be dead learning, in the understanding on the basis of mastering the drawing skills is also very important to learn the more confusing commands, strict requirements for their own standardization of drawing, to develop good habits.

　　Practice has proved that the mechanical drawing and AutoCAD two courses organically combined, the content can avoid duplication, but also well stimulate students' interest in learning, and effectively reduce the learning burden of students. Not by the rules, engineering standard

　　Note is an important basis for parts manufacturing, engineering construction and parts assembly. At any time an engineering drawing, engineering labeling is an important part of the indispensable. In some cases, engineering labeling is even more important than graphics. Only to a certain standard of strict requirements for their own, standardize their own, not afraid of trouble, really do to draw a good heart to draw a good picture, in a certain amount of time to strengthen the memory and arrangement of learning, hard work, learning more practice, theory and practice, and integration - some drawing skills, the production of CAD drawings will be able to be clear, accurate and efficient. I believe that CAD can learn the best.

　　20xx年下学期第十六周，在老师的指导下，我们班进行了为期一周的CAD制图集中实训，主要是针对轴类、箱体类和叉架类等几种常见零件的绘制，透过实训，进一步掌握CAD的应用，增强动手cao作潜质。

　　时刻过得真快，到这天截止，一周的CAD制图实训即将结束，此刻回想起刚进机房的那懵懂，自己都觉得好笑。经过一个学期的学习，应对综合量大点的图形，竟然不知从何下手。上课是一步一步，一个一个命令的学，课后的练习也没有涉及到前后的知识，知识的连贯性不大，当我们进行实际运用时，发现之前学的有点陌生。

　　实训的第一天，老师首先给我们将了这周实训的课程安排，说明了本周实训的主要资料，实训目的以及好处所在，然后交代了一些细节方面的问题，强调应当注意的一些地方，以及考试成绩打分等。听完老师的讲解后，我并没有立刻去画图，而是用两节课认真的去看任务指导书和设计指导书，很仔细的看了作图要求，以及提示的作图步骤，以便于能够合理的完成本周的实训工作，我怀着用心的心态去应对这次难得的实训机会。实训时刻安排得有点紧，尤其是周三，从中午12：00直到下午17：00，看到这样的时刻安排后，竟然没有想溜的冲动。之后我就仔细每副图的cao作细节，有些有提示，也有些没有的。我想结合我所学的，还有老师和同学的.帮忙，这周的实训肯定会有很大的收获的。

　　在接下来的几天里，我一向认认真真去绘制每一个图，思考每一个细节，作图步骤，哪怕是一个很小的问题，也都会很仔细，在作图的过程中的确遇到了不少的难题，但都在老师和同学的帮忙下，一个一个的被我击破，自己难免会感到有点惊喜，从而增强了对CAD的兴趣。

　　学习最怕的就是缺少兴趣，有了兴趣和好奇心，做什么事都不会感到累。于是我在网上找了点关于CAD的资料。CAD的发明者是美国麻省理工学院的史凯屈佩特教授，依1955年林肯实验室的SAGE系统所开发出的全世界第一支光笔为基础，提出了所谓“交谈式图学”的研究计划。这个计划就是将一阴极射线管接到一台电脑上，再利用一手持的光笔来输入资料，使电脑透过在光笔上的感应物来感应出屏幕上的位置，并获取其座标值以将之存于内存内。这个阴极射线管就算是电脑显示屏幕，那支光笔此刻可能是更先进的鼠标、数字化仪或触笔。那时候的电脑是很庞大且简陋的，但是，无论如何，这个计划开启了CAD的实际起步。事实上，此计划也还包含类似像AutoCAD这样的CAD软件，只是其在功能上的应用十分简单罢了。当交谈式图学的观念被提出且发表后，在美国，像通用汽车公司、波音航空公司等大公司就开始自行开发自用的交谈式图学系统。正因在当时，只有这样的公司才付得起开发所需的昂贵电脑设备费用和人力到了20世纪70年代，由于小型电脑费用已经下降，交谈式图学系统才开始在美国的工业界间广泛使用。在那时候，比较有名的交谈式图学软硬件系统是数据公司（Digital）的一套名为Turnkey的系统。二战后，CAD的系统也就在战后高科技军

　　事技术的转移下，导入了建设所需的铁路、造船、航空等机械重工业有名的CADAM，就是IBM公司在此期间开发出来的应用于大型主机电脑系统上的CAD／CAM整合软件。也正因它出现得很早，系统又完整，因此就将其冠以“CAD／CAM之母”的美名。

　　在电脑出现以前，产品图是在手制样品完成后再用手工画的，然后在修改手制样品后，依手制样品来制造，因此在这之前的一般用品的质量就比较粗糙而不统一。应用了CAD来绘制产品图样后，就能够配合CAM软件直接连接专业工作母机生产产品模具，使得产品在精密度、修改效益、生产效益和前后批产品的质量水准上都要比尚未CAD／CAM化前好上许多。因此，此刻除了手工艺术品外，CAD／CAM的应用率多少己成为一个国家是否属先进国家的指标。换句话说，自动化的CAD／CAM应用也是国家工业升级的重要方针之一。正因机械业也是应用CAD最早的行业，因此相关专业的CAM自然就和CAD连袂出现。事实上，在此时的CAD一词的好处就应是ComputerAidedDesign，也就是“电脑辅助设计”。正因使用CAD的人多半是设计师，而应用软件的发展方向也都是着重在某专业的辅助设计上，因此自然被称之为“电脑辅助设计”。但是我们此刻所说的CAD一般却是指“电脑辅助画图”（ComputerAidedDrafting）。这是正因此刻的CAD使用者层面已扩大，不局限于设计师使用。因此，自1985年以后，普遍就将CAD的名词统称为“电脑辅助画图”，而另用“电脑辅助设计绘图（ComputerAidedDesign&Drafting，CADD）名词来强调电脑辅助设计画图的功能。换句话说，由于时代

　　科技和应用方式的演进，有些名词的好处也会因在各自领域范畴下愈分愈细而产生变化。

September 18th incident experience Part 14

　　20xx the second semester of the sixteenth week, under the guidance of the teacher, our class carried out a one-week CAD drawing focused on practical training, mainly for shafts, boxes and fork classes and other common parts of the drawing, through practical training, to further master the application of CAD, enhance the hands-on cao potential.

　　Time flies really fast, to the end of this day, a week of CAD drawing practical training is coming to an end, at the moment recalled just into the machine room of the ignorance, they feel funny. After a semester of study, to cope with the comprehensive amount of graphics, but do not know where to start. Classes are step by step, one by one command to learn, the exercises after class did not involve the knowledge before and after the knowledge is not very coherent, when we carry out the practical application, found that the previous learning is a little strange.

　　The first day of practical training, the teacher first gave us this week's practical training course schedule, explaining the main materials of this week's practical training, the purpose of practical training and the benefits of it, and then explained some details of the problem, emphasizing that should pay attention to some of the places, as well as the test scores and so on. After listening to the teacher's explanation, I did not immediately go to the drawing, but with two classes to seriously look at the task guide and design guide, very carefully look at the requirements of the drawing, as well as tips on the steps of the drawing, in order to be able to reasonably complete the week's practical training work, I have to deal with this rare opportunity for practical training with a mindful attitude. The schedule was a bit tight, especially on Wednesday, from 12:00 noon to 17:00 p.m. When I saw this schedule, I didn't have the urge to sneak out. After that, I scrutinized the details of each pair of drawings, some of which had hints and some of which did not. I think the combination of what I learned, and the teacher and classmates . Help, this week's practical training will certainly have a great harvest.

　　In the next few days, I have always been serious to draw every picture, think about every detail, drawing steps, even if it is a very small problem, will be very careful, in the process of drawing did encounter a lot of difficult problems, but all in the teacher and students help, one by one, one by me, I will inevitably feel a little surprise, which enhances the interest in CAD.

　　The most fearful thing about learning is the lack of interest, with interest and curiosity, do anything will not feel tired. So I looked for some information on the Internet about CAD, the inventor of CAD is the United States Massachusetts Institute of Technology's Professor Shikai Chupet, according to the 1955 Lincoln Laboratory's SAGE system developed by the world's first light pen as the basis for the so-called "talk-type diagrams," the research program. This plan is a cathode ray tube connected to a computer, and then use a hand-held light pen to input information, so that the computer through the light pen on the sensor to sense the position of the screen, and get its coordinates to store it in memory. The cathode ray tube was the computer's display screen, and the light pen could be a more advanced mouse, digitizer, or stylus. The computers of that time were very large and rudimentary, but, in any case, this program gave CAD its practical beginnings. In fact, the program also included CAD software like AutoCAD, which was just very simple in its functionality. Once the concept of conversational graphics was developed and published, large companies in the United States, such as General Motors and Boeing Airways, began to develop their own conversational graphics systems. At that time, only such companies could afford the expensive computer equipment and manpower needed to develop them. In the 1970s, as the cost of small computers dropped, conversational mapping systems began to be widely used by industry in the United States. At that time, the better known conversational graphics hardware and software system was a system called Turnkey from Digital. After World War II, CAD systems were also used in the post-war high-tech military

　　The famous CADAM, which was developed by IBM during this period and applied to the mainframe computer system, is the CAD/CAM integration software that was introduced to the construction of railroads, shipbuilding, aviation, and other machinery and heavy industries under the transfer of the technology. It is also because it appeared very early, the system is complete, so it will be titled "mother of CAD / CAM" reputation.

　　Before the computer appeared, the product drawing is completed in the hand-made samples and then hand-drawn, and then in the modification of the hand-made samples, according to the hand-made samples to manufacture, so the general quality of the supplies before this is relatively rough and not uniform. After applying CAD to draw the product pattern, it can be able to cooperate with CAM software to connect directly with the professional master machine to produce the product mold, make the product in the precision, modify the efficiency, production efficiency and the quality level of the products before and after the batch are much better than before CAD/CAM. Therefore, at the moment, in addition to handmade artwork, CAD / CAM application rate has become a country whether it is an indicator of advanced countries. In other words, the application of CAD/CAM for automation is also one of the important guidelines for national industrial upgrading. Because the machinery industry is also the earliest application of CAD industry, so the related professional CAM and CAD naturally appeared together. In fact, at this time the benefits of the term CAD should be ComputerAidedDesign, that is, "computer-aided design". Just because the use of CAD is mostly designers, and the direction of the development of the application software are focused on a professional design assistance, so naturally called "computer-aided design". However, the CAD we are talking about at the moment generally refers to "computer-aided drafting" (ComputerAidedDrafting). This is because the level of CAD users has expanded and is not limited to designers. Therefore, since 1985, the general will be the CAD term collectively referred to as "computer-aided drawing", and another "computer-aided design and drafting (ComputerAidedDesign & Drafting, CADD) term to emphasize the function of computer-aided design and drafting. The function of computer-aided design and drafting. In other words, due to the times

　　As technology and applications evolve, the benefits of some terms change as they become more subdivided under their respective domains.

　　Safety, is an eternal topic, is also a clichéd topic, but for coal miners, safety is always a crucial topic, no matter who, should cherish life, in the work life to understand some of the most basic common sense to protect life safety. The importance of safety is even more indisputable for an adult working on the front line of a coal mine with an old man and a young man.

　　Recently, the district organized a study of the province in the past two years, a number of coal mine coal mine accident cases, about the real safety accidents around us, a life lost let me feel immense shock.

　　Past mistakes are future wisdom and success, and any lesson learned is a lesson learned. For the work of production safety, the lessons of accidents are also valuable assets. Parsing it, pursuing it, penetrating the mechanism, discovering the law, so as to learn by example, highlighting prevention as the mainstay, highlighting the strengthening of supervision, highlighting the implementation of responsibility, so as to promote the work. By studying some typical cases of coal mine accidents in recent years, we have further deepened our safety awareness by reviewing and reflecting on them, strengthening our awareness, publicizing regulations and imparting knowledge. Accident lessons should not end, should not pass, and should not be forgotten. Coal mine accidents to the people's lives and property, social harmony and family happiness caused by . The damage and impact of the case has enhanced our safety awareness. From the cases I found many lessons about the expansion of the consequences of accidents due to the lack of safety knowledge and insufficient safety skills, which made me realize that I need to further study safety knowledge and improve safety skills.

　　In short, only their own heart to recognize the significance of safety, understand the essence of safety, and in the work of continuous, conscious efforts to improve safety awareness, safety quality, in order to truly realize their own safety, the safety of others, the safety of the enterprise.
