At present, colleges and universities have different recognition rates for duplicate checking of graduate papers. Some schools stipulate that the duplicate checking rate is within 10%, while others stipulate that the duplicate checking rate is within 20%. Therefore, it is necessary to unify the standard of duplicate checking rate of graduation thesis among universities and establish the corresponding standard system.

In practice, some measures can be taken to reduce the duplicate checking rate of papers. First of all, we should pay attention to the writing of literature review to ensure the novelty and originality of the paper. Secondly, citing other people's research results reasonably can reduce the possibility of duplicate checking. In addition, the existence of duplicate content can be reduced by increasing experimental data and research results. Finally, we should pay attention to the structure and language expression of the paper to ensure its readability and integrity.
