There are many reasons for the high duplicate checking rate of papers. First of all, there may be more plagiarism or repetition in the content of the paper, which is one of the main reasons for the high duplicate checking rate. Secondly, the format or typesetting of the paper may not meet the requirements of schools or periodicals, resulting in a high duplicate checking rate. In addition, the duplicate checking software or database used may not be advanced or comprehensive enough, resulting in inaccurate duplicate checking results. Finally, the author may need to further revise and improve the paper to reduce the duplicate checking rate.

If the duplicate checking rate of papers is high, it is suggested that the author check and revise them one by one according to the duplicate checking report of papers. You can try to adjust the format of the paper, modify the content of the paper, increase your own views and thinking, and reduce the repetition rate. At the same time, it is suggested that the author use multiple duplicate checking software or databases to check duplicates for many times in order to obtain more accurate results.
