It should be noted that readers have no time and energy to read every paper. They often know the outline of the article through the abstract first, and then read some papers selectively. Periodicals and library and information departments also decide whether to extract and search through abstracts and keywords. When writing an abstract, the author of a periodical usually refers to the author's abstract and makes some changes. If the author's abstract is not standardized or too simple, then the abstract must read the full text of the document before writing, which is a heavy workload. At this time, although your paper is high-level, innovative and valuable, he may give up and choose the abstract that can be obtained easily, and your paper will lose the opportunity to be extracted. First of all, the abstract is a short article, which concisely and accurately describes the important contents of the paper, with the aim of providing an outline of the paper. Although there are only a few hundred words, the amount of information is as big as the paper. The content of the abstract should mainly include four elements: 1. Purpose-the purpose and task of the study, and the scope of the topics involved. 2. Methods-Methods, theories, means, conditions and materials used in the research. 3. Results-research results, data, determined relationships, obtained effects, performance, etc. 4. Conclusion-analysis, comparison, evaluation and application of the results, questions raised, future topics, inspiration, suggestions and predictions, etc. When necessary, the abstract can include the main object and scope of the research work, as well as other important information with intelligence value. It is important to reflect the new content and the author's special emphasis. The existing content in the introduction cannot be repeated in the abstract, nor can it explain and comment on the content of the paper, let alone simply repeat the existing information in the title; No common symbols and terms are used; There is no need to quote unless the paper confirms or denies the papers published by others. The structure should be rigorous, the expression should be concise, and the semantics should be exact. Abbreviations, abbreviations, and code names must be explained when they first appear, except those that can be clearly understood by readers of adjacent majors. Second, the selection of keywords is the window for academic papers to enter circulation and citation. Standardizing the selection of keywords is beneficial to the rapid and effective retrieval and citation of library and information institutions. In order to standardize academic papers, deepen the research and statistics of academic documents, improve the level of multi-level literature retrieval, and make more academic papers enter the citation category of scientific and technological work, China Association for Science and Technology stipulates that all academic papers published in academic journals of China Association for Science and Technology should be selected in the following order: The first keyword lists the names of the two disciplines to which the main work or content of this paper belongs. The titles of the papers published in Operation and Management are: operations research, probability theory and mathematical statistics, applied mathematics, fuzzy mathematics, regional economics, industrial economics, finance, international trade, national defense economy, system theory, system analysis and integration, accounting, enterprise management, tourism management, technical economy and management? . The second keyword lists the names of the results obtained in this paper or the total class names of several results in this paper. The third keyword lists the specific names of the scientific research methods used in this paper to get the above results or conclusions. For summary and critical academic papers, this position is written as "summary" or "comment" respectively. In the research paper on scientific research methods, the name of the method being studied is not written here, but the name of the method being applied. The former appears in the position of the second keyword. The fourth keyword lists the names of things or substances that do not appear in the first three keywords, but are the main research objects of this paper, or nouns that appear in the title and the author thinks are important. When necessary, the fifth and sixth keywords list other keywords that the author thinks are beneficial to retrieval and literature utilization. When selecting keywords, you should not use non-public technical terms and their abbreviations; Synonyms and synonyms should not be juxtaposed as keywords. Many authors don't attach importance to abstracts and keywords. The abstract of a paper of seven or eight thousand words contains only one sentence. Key words are also two perfunctory words. It should be noted that readers have no time and energy to read every paper. They often know the outline of the article through the abstract first, and then read some papers selectively. Periodicals and library and information departments also decide whether to extract and search through abstracts and keywords. When writing an abstract, the author of a periodical usually refers to the author's abstract and makes some changes. If the author's abstract is not standardized or too simple, then the abstract must read the full text of the document before writing, which is a heavy workload.
