The paper should include the following parts. To write a good paper, you should follow the following requirements: the first page of the paper, including Chinese abstracts such as the title and company name, English abstracts of keywords and the text of keyword list (including introduction or preface), and pay attention to the chart and annotation format, reference appendix (optional) 1 and title of the paper, and reflect the most important content of the paper properly and accurately with concise words (generally no more than 20 words). Thesis topics are usually composed of noun phrases, so we should try to avoid using uncommon abbreviations, acronyms, characters, codes and formulas. If the content of the paper is multi-layered and difficult to simplify, the method of combining the title and subtitle can be adopted, in which the subtitle plays a role in supplementing and clarifying the title. Headlines and subheadings should be consistent when they appear in different positions throughout the paper. 2. Abstract is a brief statement of the content of the paper. It is an independent and complete essay, usually written in the third person tone, without comments or supplementary explanations. Should be independent and self-sufficient, that is, you can get the necessary information without reading the full text of the paper. Generally, the purpose, methods, results and conclusions of the research work should be explained, with emphasis on the results and conclusions. Generally, the number of Chinese abstracts is 300~600 words, while the number of substantive English abstracts is about 300 words, which can be slightly more if there is special need. As far as possible, unknown and common figures, tables, chemical structures, symbols and terms should be avoided. 3. Keywords keywords (including Chinese and English keywords) are words or terms that express the content information of the paper, which should reflect the characteristics of the paper, have semantics and have a clear source in the paper. The number of keywords is generally 3-8, and each keyword is separated by a semicolon. There is no punctuation after the last keyword, and Chinese and English keywords should correspond to each other one by one. Chinese keywords should be marked with "Keyword:" and English keywords with "Keyword:". 4. The table of contents is a sequential list of chapters in the paper. Papers should be written in a table of contents and marked with page numbers, so as to facilitate reading and mastering the main contents of the papers. The level of the directory should not exceed level 3. 5. The text includes: introduction (or preface, preface), this theory and conclusion. (1) Introduction: It is the beginning of the paper, including the following contents: ① Explain the purpose and significance of writing the paper and the understanding of the research issues; 2 ask questions. (2) This theory is the main body and the most important part of the paper, and the whole argumentation process is carried out here. This theory generally includes: ① according to the needs of the central argument, determine the sub-arguments and arrange the levels and paragraphs of the article; (2) Put forward arguments and discuss them. (3) Conclusion: It is the end of the paper, which mainly includes three parts: ① the conclusion put forward or emphasized; (2) Prospect of the future development trend of the research; (3) A brief description of relevant issues. (General requirements for science and engineering majors and economic management grammar majors 10000~ 15000 words). 6. Reference is a collection of documents with specific sources cited in this paper, which is an indispensable part of the paper and the author's recognition and respect for other people's knowledge achievements. There are many references 10 in this paper, including at least 2 foreign references. 7. Appendix According to the content requirements of the paper, determine whether an appendix is needed. Including the formula derivation that is too lengthy in this paper, the auxiliary mathematical tools that others need to read easily, the repeated data charts, the symbolic meanings used in the paper, etc. So, how to write a good paper? The first is the topic selection. Topic selection is the key to success or failure of thesis writing. Because choosing a topic is the first step in writing a paper, it is actually to determine the question of "what to write", that is, to determine the direction of scientific research. If "what to write" is not clear, "how to write" is impossible. Specifically, the topic can be selected from the following three aspects. First of all, we should choose a topic from the disadvantages of reality and learn professional knowledge. We should not only stay in books and theories, but also try to integrate theory with practice and use our professional knowledge to find and solve problems that need to be solved urgently in work practice. Secondly, we should choose topics from the blank and marginal fields of scientific research. There are still many virgin lands in scientific research, and there are still many defects and gaps to be filled. The author should have a unique vision and advanced consciousness to think, discover and study. Finally, we should choose the topic from finding the shortcomings and mistakes of previous studies. Many of the research topics put forward by predecessors have achieved initial research results, but with the continuous development of society, they still need to be enriched, improved and developed. This supplementary or revised research topic also has scientific value and practical guiding significance.
