The so-called number of words in a paper includes the number of words in abstracts and references. Generally, the number of words is about 300, which is short and pithy. The following are the relevant requirements of several parts in a paper.

Nowadays, papers are often used to refer to articles that study various academic fields and describe academic research results. It is not only a means to discuss problems and conduct academic research, but also a means to describe academic research results and conduct academic exchanges.

Keywords and definitions:

Keywords are selected from the title, abstract and text of the paper. They are meaningful words that express the central content of the article. Keywords are words used by computer systems to mark the content characteristics of papers, so as to facilitate the collection of information systems and provide readers with retrieval. Generally, 3-8 words are selected as keywords for each paper, and a single line is placed at the lower left of the "abstract".

Subject words are standard words. When determining the subject words, we should analyze the subject words according to the indexing and matching rules and convert them into standard word in thesaurus. (See China Synonymy Dictionary and World Chinese Synonymy Dictionary).
