Modify the text: This is the most effective way to reduce the repetition rate. You can reduce the repetition rate by changing the sentence structure, replacing keywords with synonyms, and breaking down long paragraphs into short ones.

Use references: If you refer to other files, remember to use the correct reference format. This can avoid being considered plagiarism.

Use paper duplicate checking software: You can use some special duplicate checking software, such as paperfree, to help detect the repetition rate of papers.

Avoid copying and pasting directly: When writing a paper, avoid copying and pasting the contents of other articles directly. Even a short paragraph may increase your repetition rate.

Translation of foreign documents: translating some contents with high repetition rate into foreign documents and then re-expressing them in your own words can effectively reduce the repetition rate.

Generally speaking, as long as the formal duplicate checking system is used, duplicate checking will not affect the repetition rate of papers. Because the regular duplicate checking system will identify the duplicate content according to the semantics of the paper every time, it will not increase the repetition rate because of the increase of duplicate checking times.
