It is not only a means to discuss problems in academic research, but also a tool to describe academic research results in academic exchanges. Including academic papers, graduation papers, dissertations, scientific papers, achievement papers and so on.

After the paper is published, the abstract can be directly used by abstract magazines or various databases without modification or slight modification, so that readers can know the main contents of the paper as soon as possible to supplement the deficiency of the title, thus avoiding misunderstandings, deficiencies and even mistakes that may occur when others compile the abstract. Therefore, the quality of abstracts directly affects the retrieval rate and citation frequency of papers.
