In academic papers, the correct understanding and interpretation of symbols is very important. The following are some guidelines for the correct use of symbols:

-In all parts of the paper (including title, abstract, body and explanatory text of each chart), please explain the meaning of an abbreviation when it is used for the first time. Each abbreviation has a specific application field, such as interlacing like a mountain.

-Use punctuation marks: Punctuation marks play the role of separation and connection in the article.

-Provide clear names for symbols to ensure that the names of symbols can accurately reflect the concepts or variables they represent.

-Provide a complete definition of the symbol before the first use. This can be done in an appropriate place in the paper, such as in the research method or introduction.
