Title, author, abstract, key words, introduction, text, conclusion, thanks and references. Title title, also known as title, paper title and title, is the center and general outline of scientific and technological papers. Requirements are accurate and appropriate, concise, eye-catching and standardized, and easy to retrieve. Taboo skin big stuffing small, blindly arrogant, word repetition, word order confusion. It is indeed appropriate to ask the title of the paper to accurately express the content of the paper and properly reflect the scope and depth of the research. Common faults are: too general, the topic is not deducted. The key problem is that the topic should be closely related to the content of the paper, or that the content of the paper should be closely related to the topic, that is, the topic should be deducted and the article should be deducted. This is the basic principle of writing a thesis. Be concise and to the point, with fewer words and precise choice of words. As for how many words are qualified, there is no uniform "hard" rule. It is generally hoped that the title of the paper will not exceed 20 words. However, the pursuit of fewer words should not affect the proper reflection of the topic in content. When there is a contradiction between the two, it is best to use more words and express them as clearly as possible. If the short title is not enough to show the content of the paper or reflect the nature of a series of research, it can be solved by positive and negative titles, and the specific experimental materials, methods and contents can be supplemented by adding negative titles, so that the titles can be enriched and accurate, rather than generalized. Eye-catching standards facilitate retrieval. Although the title of the paper is in the first eye-catching position to attract readers' attention, there is still the problem of whether the title is eye-catching, because whether the words used in the title are eye-catching or not is far from the effect. The words used in the topic should use the standardized words in the keyword list as much as possible, so as to facilitate the citation and retrieval in the dissemination of the paper. In addition to the general title, scientific papers generally have hierarchical titles. Rank titles refer to all ranks of titles except titles. It is usually divided into chapters, sections, articles and paragraphs. Hierarchical titles can make the whole content structure clear; From the content point of view, it is a summary of the central content of each chapter and section, which is actually the so-called "outline" inspired by generate. Before drafting, there must be a conception stage. Conception is an abstract grasp and design of the whole article, focusing on abstract thinking. Simply speaking, the idea is to think as a whole and "think" about the article. Outline is the externalization and achievement of thought, which is actually equivalent to a chart composed of serial numbers and text symbols. The function of the outline is to guide the drafting and visualize the thinking, so that the author can grasp, modify and improve it more accurately and generally. An outline should be prepared for all paper writing. Writing an outline itself is learning and drafting. As long as it is constantly enriched, the outline will become the first draft of an article. Signature means that the author declares that he owns the copyright of the paper and is willing to take responsibility for it, so that readers can contact the author conveniently. Signature includes work unit and contact information. The work unit should write the full name, including the city name and postal code. Sometimes, for literature analysis, the author is required to provide information such as gender, date of birth, professional title, telephone number and email address. It is a brief statement of the content of the paper, without comments and annotations, and it is a high summary of the content of the article. The main contents include: 1) the content, purpose and importance of this research work. The experimental methods used. Meaning: The abstract does not list examples, describe the research process and make self-evaluation. Keywords keywords are words, phrases or terms extracted from papers to meet the needs of document indexing or retrieval, which represent the information items of the full text theme. General keywords 3 ~ 8 are literature retrieval marks of scientific papers and natural language vocabulary, which are used to express the concept of literature theme. The key words of scientific papers are selected from the title, hierarchical title and text of the paper, which can reflect the theme of the paper. Keywords are put forward to meet the needs of computer retrieval, and the position is after the abstract. As early as 1963, the American Chemical Abstracts rolled up from page 58 and began to use computers to compile keyword indexes, which provided a quick way to retrieve literature topics. Today, with the rapid development of scientific and technological information, hundreds of thousands of scientific and technological papers are published every day all over the world, and academic circles have long agreed to use subject concept words to retrieve the latest published papers. If the author's published papers are not marked with keywords or descriptors, such articles will not be included in the literature database, and readers will not be able to retrieve them. Whether the keywords are properly selected is related to the retrieval of this article and the utilization rate of this achievement. Keywords classification keywords include narrative words and free words.
