1. The content that has become common sense in this field should be excluded from the abstract: it is forbidden to write what should appear in the introduction into the abstract, and generally do not interpret and comment on the content of the paper (especially self-evaluation).

2. Don't simply repeat the information already in the title.

3. Rigorous structure, concise expression and exact semantics. What to write first, then what to write, should be arranged in logical order. Sentences should be coherent and echo each other. Use long sentences with caution and keep them as simple as possible. Every sentence should be clear, and there should be no vague, general or vague words, but the abstract is a complete essay after all, and telegraph writing is not enough. The abstract is not segmented.

4. Use the third person. It is suggested that the description methods such as "researching …" and "reporting the present situation" and "investigating …" should be used to indicate the nature and theme of the literature at one time, and it is not necessary to use "this article" and "author" as subjects.

5, to use standard terminology, not open symbols and terms. If there are new terms or no Chinese terms, you can indicate the original text in brackets or after the translation.

6. In addition to being really inflexible, mathematical formulas and chemical structural formulas are generally not used, and there are no illustrations and tables.

7. There is no need to quote unless the document confirms or denies the published works of others.

8. Abbreviations, abbreviations and codes must be explained when they first appear, except those that can be clearly understood by readers of adjacent majors.
