1. Why do you have to write a paper? Dissertation is an important basis for applying for and awarding corresponding degrees, because it is a summary of graduate students' research achievements during their study and research work, and represents their research achievements and academic level. You can't graduate without writing a thesis. There are laws to follow. It is stipulated in the Regulations on Academic Degrees in People's Republic of China (PRC) issued in February 1980. At present, a new degree law is being drafted. Second, the structure of the paper The structure of the paper mainly includes title, abstract, key words, contents, body part, conclusion, references and thanks. 1, the topic should be exact and solid, generally no more than 25 words, and punctuation marks should be avoided as far as possible, preferably no dashes. The level of selected papers can be improved at once, which can attract click-through rate and expand the influence radius in retrieval. For example, these two topics: a\ Formula derivation and structural design of aviation gear reducer; Modeling and optimization design of aviation gear reducer. These two topics can be put on the same test paper, but they give people a completely different feeling. The former is an undergraduate thesis and the latter is a master's thesis. 2. The abstract is divided into Chinese and English. Word requirements for Chinese abstracts: 500 ~ 1000 for masters and 0/000 ~ 2000 for doctors. At the end of the whole process of thesis writing, it includes the purpose, method, result, innovation, practical significance and application value of the research. Language should be accurate and clear, and words such as "probably" and "probably" should not be used. Don't write in the first person, just don't write in person. No spaces, writing a long paragraph can be used in any article, and it will not have any characteristics and significance. Don't write "material stiffness reaches%%, hardness reaches%%, strength reaches%%, surface roughness of parts reaches%%", which is too thin. 3. There are about five key words, and the epitaxial layer is from large to small from left to right. Such as: mechanical parts. Keywords are also used for retrieval, which should reflect the main content of the article. 4, the table of contents should pay attention to the writing of chapter titles, this chapter has instructions for reference, no need to elaborate. 5. The text is generally four or five chapters, and the number of chapters should not be too much. The key is to have content. Papers with the same number of chapters have different gold contents. The first chapter of the text is the introduction. Don't copy the abstract, don't deduce the formula, and write about 7 to 9 pages. The research content of the introduction includes the background and research purpose (meaning) of the subject, that is, the problem that others have not solved but I want to solve. And the current situation at home and abroad. Be careful not to write too long, but write more in recent years. Then it is the main research content of the paper, which can be written in terms. The second chapter to the fourth chapter or the fifth chapter is about what you have learned, and this part of the paper should be more than 40 pages. This part is the main body of the paper, and it is the display and expression of the author's research results. It makes a comprehensive and thorough analysis and demonstration of the research contents in the introduction, and fully expresses the author's views. Generally speaking, it includes concept presentation, theoretical demonstration, method selection, formula derivation, experiment and experimental data processing, and result analysis. Note: Chart A is clear, and if quoted, there must be a submission number; B can't be copied into chapters, the formula should not be written too carefully, and the calculation process of specific values need not be written in the paper; Chapter c should have a section. 6. Conclusion Shuo Yan's conclusion is 1000 to 1500 words, which can't be written like an abstract. The conclusion consists of three parts: one is the summary of the full text; Second, innovation results, innovation results generally do not exceed four, each of which does not exceed five or six lines; Third, looking forward to the work that needs to be continued in the future, there can be several lines above, usually 2 to 3 lines. 7. References There are 40 to 50 references for master's theses, which must be published papers, and try to quote the latest papers, at least one third of which are in English. 8. Thank you. Thank you sincerely, and thank those who helped you with your paper. Words should not be too flowery, too sensational, realistic and heartfelt. Don't thank people who have nothing to do with the paper but are helpful in other ways. Third, the latter emphasizes the authenticity of the paper, and the consequences of plagiarism are very serious! Some famous universities have had a bad influence because of plagiarism scandals. In the blind trial, it was found that some papers were plagiarized, and even the names of the people who thanked them were not changed. Personally, I think graduate thesis should be done by myself, not as required as undergraduate thesis. After all, what you have learned is your own, and other people's articles may be used to muddle through graduation, but if your head is empty, you will miss the stuffing sooner or later. At that time, people said they were still graduate students! Isn't it shameful? In addition, the specific requirements of each school will be different, so the above standards cannot be ignored word for word. But this is the general idea. After all, lecturers have been engaged in higher education for many years and are still very experienced.
