篇一:机械实习总结 参考文献 致谢

总 结

到此为止,在自己三个月的努力后顺利完成了CA6140拨叉的机械制造工艺及其夹具设计。从刚开始对制造工艺只有一点感性认识到现在已熟悉制造工艺的国内外现状及趋势,能对工件确定合理的工艺方案,对零件的设计制造,机床设备的选用,机械零件的选用及零件加工工艺过程的说明有了较为深刻的领会,同时对根据加工工艺设计相应的夹具体也较清楚。

在本次设计中,要用到许多基础理论,由于有些知识已经遗忘,这使我们要重新温习知识,因此设计之前就对大学里面所涉及到的有关该课题的课程认真的复习了一遍,开始对本课题的设计任务有了大致的了解,并也有了设计的感觉。同时,由于设计的需要,要查阅并收集大量关于机械制造方面的文献,进而对这些文献进行分析和总结。通过本次设计还使我更深切地感受到了团队的力量,在与同学们的讨论中发现问题并及时解决问题,这些使我们相互之间的沟通协调能力得到了提高,团队合作精神也得到了增强。可以说,毕业设计体现了我们大学四年所学的大部分知识,也检验了我们的综合素质和实际能力。同时也跨出了我的工程师之路的第一步。

虽然本次设计我很努力去做,但还是存在一些不足:

(1)我对机械工艺规程设计理论方面的知识还没有十分扎实,对并没有投入生产,在实际生产中的产品,还要根据生产部门的设备,要求等,考虑零件的结构,精度和余量,难免会有我们现在没有考虑周全的内容。

(2)对零件热处理方式及夹具的设计把握不准,其主要原因是对零件的了解不足,没有在真正的实践,而且没有见过实体,一些细节部分没有掌握好。

(3)夹具设计是本次设计中最大的拦路虎,虽然课题(来自:WWw.cssyq.Com 书业网:食品专业实习致谢)要求我们只要选择其中之一工序进行夹具设计,但是夹具设计过程中遇到的问题是最多的,特别是对各机构的选用,既要达到局部要求,又要配合整体要求。因此我以后必定会再这方面多下苦功。

因此,在以后的学习工作中,我要从以下方面来提高自己,解决设计中存在的问题。多学习相关的知识,关注前沿的科学技术,拓宽知识面,尽量进行实践,以便设计时能够在保证成本的前提下,较好地利用其本身。

致谢

为期三个多月的毕业设计就要结束了,我也顺利的完成了我的课题设计,在此之际我要衷心的感谢在设计过程中一直帮助我支持我的老师。

我要感谢指导老师——李晓静老师,李老师在整个设计过程中对我的影响很大,设计过程中的很多个难点都是在郭老师的悉心指导下才克服的,还有李老师亲切和善也是我在整个设计过程中感受最深的。也因为这样,和老师之间存在着师生心理障碍一下全无,我也就大方的有问题就问,有想法就提,这也使得我能更多的发现设计中存在的问题,并解决问题。李老师严谨的治学态度,渊博的专业知识,诲人不倦教学精神,在学术上和为人上都是我们的楷模和榜样。同时我还要感谢跟我一起参与设计的同学,虽然我们课题不同,但是都能在讨论中发现各自的问题,并互相提出解决的方法,设计能够顺利完成,也因为他们的帮助。

结束代表着新的开始,新的征程,本次的毕业设计将会成为我今后工作,学习生活中的一份坚实的基础和保证。从中吸取的经验教训也将成为我们在今后生活道路上的一笔财富,挫折永远是前进道路上所必须面对的,相信我们的未来会走的更好,也可以让我们大学的老师放心。真心的感谢在大学帮助过我的老师和同学们,再次感谢你们!

ACKNOWLEDGEMENTS

Upon the completion of this thesis, I avail myself of this opportunity to express my heartfelt gratitude to all those who have given me lots of help and support during my preparation of this thesis.

First and foremost, a special acknowledgement goes to my supervisor, Professor Ma Songmei, who has spent a lot of time reading portions of my manuscript and helping improve its quality. I feel grateful for her invaluable suggestion, careful corrections, selfless help and strict demands. Her help has been essential for me to avoid or forestall errors and difficulties of some kinds. My hearty gratitude also goes to all the other faculty members of the English Department, from whom I have learned a lot of comprehensive knowledge and insightful ideas.

Moreover, I feel indebted, in my process of immersion in the preparation for this thesis, to many authors and scholars, from whose works I have profited indispensable help profusely. Their critical spirit as well as writings has either inspired me in my reading or directly eiched the survey in the form of loaned information.

Last but not least, I want to extend my sincere thanks to my parents and classmates for their constant support and encouragement.

If I stand tall, it is because I stand on the shoulders of giants. The sky is the limit for my gratitude to those listed above.

ABSTRACT

The study of the cultivation of students’ pragmatic competence has been investigated actively in recently, while there is less research on the cultivation of students’ pragmatic competence in primary school. Although some studies of this field have been conducted, there is no a complete analysis about the causes of students’ pragmatic failure and there is no systematic methods and teaching strategies to solve these problems. The present investigation aims at exploring the existing problems about students’ pragmatic failure and finding the causes of these problems and then seeking out the strategies to cultivate students’ English pragmatic competence. This study was conducted through observation of students’ use of English and English classroom teaching in several primary schools. After observation and analysis, results show that students’ pragmatic failures are related to the many factors, including the way of English teaching in primary school, the effect of the native language, the lacking of the knowledge of English culture and so on. In view of these findings, some strategies were listed to help to cultivate and improve students’ pragmatic competence in primary school and to improve the quality of English teaching in primary school.

Key Words: pragmatic competence; primary school; English teaching; cultivation;

strategies.

摘 要

学生的英语语用能力是语言交际的关键,长期以来,关于学生英语语用能力培养的研究有很多,但是对小学生语用能力的培养却很少。对学生英语语用能力的研究也很少完整的分析学生语用失败的分析,并未提出系统的方法与策略来解决这些问题。这篇论文旨在探讨小学生英语语用失败的原因,以及找出相应的解决策略来培养和提高小学生的英语语用能力。本文通过观察分析法来研究,并对几所小学英语教学以及学生使用英语的情况的观察,分析存在的问题,以及根据存在的问题找出相应的解决策略,提高小学生英语语用能力,从而提高整个英语教学的质量。
