After all the contents of the paper are compared, the repetition rate will be calculated, that is, the proportion of repeated parts in the whole paper will be calculated. The purpose of the paper is to check the repetition rate of the paper, so why check the paper? There are natural reasons, and the purpose of duplicate checking is to reduce and prevent plagiarism, that is, to stop academic misconduct; It is more meaningful to get effective methods to improve the quality of teaching papers at a certain level of education and promote the healthy and benign economic development of educating students' learning atmosphere.
