1 Title is an indispensable part of scientific papers. It requires the most concise and appropriate phrases to reflect the specific content of the article and clearly tell the readers the theme of the paper. Generally speaking, the title should include the main keywords of the article. China sci-tech periodicals, the title of the paper shall not exceed 10. Author's signature is an important part of scientific papers. The author refers to the person who has made great contributions to the conception of the theme of the paper, the implementation of specific research work, writing and writing. Who can be responsible for defending the main content of the paper is the legal sovereign and responsible person of the paper. When the author's name is given, his work unit and mailing address should also be given. Abstract is a short article that concisely and accurately describes the important contents of literature, without comments or supplementary explanations. Generally, the purpose, methods, results and conclusions of the research work should be explained. It is a necessary additional part of scientific papers, and only short articles can be omitted. Pay attention to the following points when writing an abstract: 1) Exclude the content that has become common sense within the scope of this discipline. 2) Don't simply repeat what has been said in the topic. 3) It requires strict structure, precise semantics, concise expression and one go, and generally does not divide or attempt to divide paragraphs, avoiding vague comments and making ambiguous conclusions. Articles that are inconclusive can be briefly discussed in the abstract. 4) Chinese abstracts are generally no more than 200~300 words; Foreign language abstracts should not exceed 250 real words. In case of special needs, the number of words can be slightly more. In some specifications, it is also clearly pointed out that "English abstracts should correspond to Chinese abstracts". 5) Write in the third person, and don't use "I", "author" and "we" as the subject of the statement; Narrative methods such as "research", "reporting the present situation" and "investigation" should be adopted. Although this provision is controversial, scientific and technological publications must still follow this standard before the relevant departments issue new standards. 6) Standardized terminology should be adopted. If there is no suitable Chinese translation of the new term, you can use the original text or the translation name with brackets to represent the original text. 7) Don't use charts, tables or chemical structures, and abbreviations, abbreviations and codes that are difficult for neighboring professional readers to clearly understand. If it is really necessary, it must be explained when the abstract first appears. 8) The chapter number, drawing number, table number, formula number and reference contribution number listed in the article shall not be used. 9) Necessary trade names shall be marked with scientific names. 10) legal units of measurement shall be used. 4 Keywords After the abstract, you should give 3~8 keywords that can reflect the characteristics of the article and have strong versatility. 5. The chapter number of the article should comply with the relevant regulations, and the chapters of scientific papers should be written in Arabic numerals at different levels, that is, the number of the first-level title is 1, 2 ...; The number of the secondary title is1.1.1.2 ... 2.1,2.2 ...; The number of the third-level title is1.1.1.1.1.2, and so on. 6 Introduction Introduction is often used as the beginning of scientific papers, which mainly answers the question "Why research". This paper briefly introduces the background of the topic, the history and present situation of previous research in related fields, and the author's intention and analysis basis, including the pursuit goal, research scope, theory and technical scheme selection of the paper. Introduction: Don't elaborate on the familiar knowledge of peers, including the basic theories, experimental methods and derivation of basic equations that have been mentioned in textbooks. The text is the core part of scientific papers, which mainly answers the question of "how to study". The text should fully explain the viewpoint, principle, method and the whole process of achieving the expected goal, highlight the word "new" and reflect the originality of stationery. According to the need, the paper can be deeply layered, analyzed layer by layer, and set layered titles by layer. For scientific papers, clear thinking, strict logic, concise, accurate, vivid and fluent language are required; The content should be objective, scientific and complete, and use facts and data as much as possible. Writing a paper should adhere to the principle of seeking truth from facts and a rigorous scientific attitude, especially paying attention to accuracy. There must be no academic (or technical) errors in data collection, recording, collation and expression. When describing facts, introducing situations, analyzing and discussing problems, we should choose words and make sentences accurately, and strive to avoid ambiguity and ambiguity. Formulas, data, charts, words, symbols, etc. What is given should be accurate, and there should be no subtle omissions. Please refer to the appendix for basic specification requirements such as tables or charts (functional diagrams). ) should be self-explanatory, that is, the information you give can explain the problem you want to express. The citation of data should be rigorous and accurate, to prevent misquoting or re-quoting, and to avoid repeating the same set of data with charts. The citation of materials should indicate the source. Physical quantities and unit symbols should adopt the provisions of legal units of measurement in People's Republic of China (PRC), and adopt standardized units and text symbols; When we have to choose non-standard units or symbols, we should consider industry habits or use legal units and symbols for annotation and conversion. Avoid re-describing and demonstrating the existing knowledge, and try to use the method of marking references; For some mathematical derivation used, the form of appendix can be used for readers to choose and read when necessary. Conclusion The conclusion (or discussion) is the final summary of the whole article. Although most authors of scientific papers end with conclusions, this is not a necessary part of the paper. Conclusion It should be completely, accurately and concisely pointed out that: 1) the principle and universality revealed by the investigation or experimental results of the research object; 2) Whether there are any exceptions in the research or problems that are difficult to explain and solve in this paper; 3) Similarities and differences with previously published research work (including others or the author himself); 4) The theoretical and practical significance and value of this paper; 5) Suggestions for further research on this subject. 9 Description of Fund Projects Fund projects refer to the funding background of article output, such as the National Natural Science Foundation and the Doctoral Program Fund of the Ministry of Education. Any article that receives the output from the fund shall indicate the name of the fund project (the official name stipulated by the relevant state departments) and the project number. A number of fund projects should be listed in turn. Such as: fund project: supported by National Natural Science Foundation of China (59637050); National Science and Technology Public Relations Project during the Eighth Five-Year Plan (85-20-74). Fan Wen: Freshman experience (1) I have been living in college for almost a year. At this time, I still don't know where to go, and I don't know what to do about the future ... for a while, I felt lonely and depressed. I don't think my college classmates know and understand me as much as my high school classmates. They often don't mean to hurt me because they don't know me well. They seem to only see my surface and ignore my inner feelings. Whenever this happens, I miss my high school classmates very much. So sometimes I become very silent. Of course, in my usual style, they won't notice my mistake. Because I have a good self-adjustment ability, no matter how unhappy I am, after my temporary "self-isolation", I "fantasize" or read books like "Little Stories and Great Wisdom", and gradually I will come out of the storm and return to my lively and cheerful self! Here, I know myself more and more. I find that I care about what others think of me, and I seem to live in what others say. For example, I will be sad for a long time because of an unintentional sentence from others. Take an old friend of mine as an example. She is straightforward and doesn't seem to consider other people's feelings when she speaks. Whenever something doesn't suit her personal wishes, she will fly into a rage (this word may be a bit exaggerated). Maybe her personality is nothing to others, but it is different to me. I am happy to say that I am good, and I am uncomfortable to say that I am not good. I seem to live completely in her words. I am so hard! How I want to get rid of it! Of course, I know that if you want to improve your living environment, you must change yourself first, because you can't change others. There is a saying that "you will be safe when you come." You can't change the environment, just try to change yourself! I must seriously think about what I really need. I must evaluate myself correctly. I can't live forever in other people's words-a slip of the tongue makes a horse stumble. (2) When studying and living in middle school, teachers will repeat the key contents of each lesson over and over again, but after entering the university, teachers will only play the role of guides. Students must study, explore and practice independently, and their self-study ability must also be cultivated during the university. Many students (including me) always complain that teachers don't teach well, don't know much, and the school curriculum is unreasonable. In fact, we complain that our teachers don't teach well because our learning methods and attitudes are still in the middle school stage. In college, our previous learning methods are no longer applicable. We shouldn't follow the teacher, but should take the initiative to chase the teacher. For example, a university teacher (such as Mr. Zheng) usually covers dozens of pages in a class, and it is impossible to learn the knowledge thoroughly only by attending classes. So I will browse the courses I will study before class, but sometimes I can't keep up with the teacher's rhythm because I am lazy, and I can imagine the end. "College students" said that a good learning method should be to ponder the related problems in the textbook before the teacher gives a lecture, and then make up for the lack of understanding and comprehension by comparing the teacher's courseware in class. Having said that, it really makes sense. I believe that every student (especially a good scholar) understands the principle of preview before class, but I think that if a student's self-awareness is not high, there is no reason to shine. So I gradually realized that the best learning method should be to improve his self-awareness. Middle school students should pursue "remembering" knowledge when learning knowledge, while college students should ask themselves to "understand" knowledge and be good at asking questions. For each knowledge point, they should ask "why" more. When learning knowledge and solving problems, don't always stick to a mode of thinking, and don't make yourself a slave to textbooks or experience. College students should also make full use of libraries and the Internet to cultivate the ability of autonomous learning and research. In addition to the courses prescribed by the teacher, you should also learn to find books and documents. This is what "college students" say, and it is the last word. Speaking of which, I have something to say. Marx said that the internal cause is the basis of the change and development of things, and the external cause is the necessary condition for the change and development of things. Before I came to the university, I made up my mind to regard the library as one of my university's "homes", but after I came, the library here disappointed me, and I couldn't find any books and documents corresponding to my major at all. Multimedia is the same, the network speed is very slow, and sometimes even the Internet can't be accessed. Excuse me, can students study hard in such an environment? So I must repeat, no matter how good the truth is, it must be analyzed in detail! (3) The end of college life is rich and colorful, which provides us with a bigger platform to play your personal charm. Let's ignore the unpleasant things together and actively meet the challenge of tomorrow! Because, I believe tomorrow will be better-don't be sad for yesterday, don't worry about tomorrow, make good use of today!
