Duplicate checking refers to the original paper detection method, also known as the paper detection system. The duplicate checking system will compare the papers uploaded by everyone with the database in the duplicate checking system, and through a specific algorithm, it will detect the most intuitive embodiment of duplication with other people's papers, so as to intuitively see how many parts of the paper may be plagiarized.

It is inevitable to quote some other people's papers and materials when writing a paper, which will directly affect the repetition rate of the paper. However, if you mark the reference format, you can distinguish it by repeatedly checking the system. If it is directly copied content, rather than quoted content, then you need to modify this part of the content to reduce the repetition rate.

Please note that each university will set up a qualified standard for paper duplicate checking rate, and it is recommended to know about its own duplicate checking rate standard.
