The referenced file is included in the duplicate checking scope. The paper duplication checking system will compare the documents cited in the paper with the existing literature database to check whether there is duplication or plagiarism. Therefore, when writing a paper, you must cite references reasonably and indicate the source to avoid unqualified duplicate checking caused by repetition or plagiarism.

It should be pointed out that different duplicate checking systems may treat the cited documents in different ways. Some duplicate checking systems can identify and process referenced documents to some extent. These paper duplicate checking systems can automatically identify the cited parts according to the citation format, but the plagiarized parts will still be marked in red. Therefore, when writing a paper, it is necessary to know the specific provisions and requirements of the selected duplicate checking system in order to better quote and check the documents.
