Quoting someone else's abstract in the paper should be counted as a reference to this document, because this abstract comes from the content of this document and also plays the role of quoting the document. Therefore, when citing other people's abstracts in a paper, the document should be listed as a reference, and the appropriate citation format should be marked at the place where the abstract is quoted, such as indicating the author, year, page number or paragraph number of the document in brackets. At the same time, it is necessary to fully quote the cited documents in the list of references at the end of the paper.
