How to write the introduction part of the paper? Please help me analyze it

First of all, explain the basic content of your research field:

Try to be concise and clear, not wordy; It should be noted that readers are experts in this field, so some obvious knowledge should be described in general rather than narrative language.

Second, literature review:

Yes, this is one of the highlights of our introduction, and we need to pay special attention to pen and ink to describe it. On the one hand, it is necessary to comprehensively summarize the past and present situation in this field, and there should be no omissions, especially the latest progress and the quotations from past classic documents (these are the two most prone places, which should be avoided as far as possible; Once the reviewer points out these two faults, it is likely that your work is not thorough or comprehensive enough, and the negative impact is very obvious).

On the other hand, literature citation and data provision must be accurate, and it is important to avoid extracting partial results unilaterally without reflecting the overall results of the literature; The quoted data should also be correct, especially the indirectly quoted data (that is, the data of another document found in other people's literature rather than the original data); Data errors will lead to poor impression of the article! In addition, when quoting documents, pay attention to avoid giving people the impression of plagiarism, that is, don't copy the original text, but summarize and describe it in your own words. If the reviewer happens to be the citation of the document, the result of copying the original text will be very bad.
