Inquiring about relevant public information shows that the references in the paper correspond to the cited documents, which refer to published opinions, articles or experimental results, and the quoted contents should be marked with [1][2]. The order of the "references" listed at the end of the article needs to correspond to the superscript in the article. Footnotes are generally on the first page of the article and the lower left of the text, which are the author's personal information, such as the author, source and other information or the correspondent's information.

After the paper is completed, it is usually published, not the reading report, experimental report or data processing report recorded by itself. Papers can generally be divided into periodical papers and non-periodical papers (dissertations, conference papers, etc.). ). Various publishing platforms and specific papers need references and other citation formats. Generally speaking, published references are put forward in the form of references. Some rare special cases need to be explained in footnotes, but they should not be repeated. In addition, some journals are required not to use footnotes.
