Synonym replacement: When quoting a document, you can replace the words in the original text with synonyms, which can reduce the duplicate checking rate.
Change the sentence structure: rewrite the sentence structure of the cited documents, for example, change the passive voice to the active voice, or change long sentences to short sentences to reduce the repetition rate while keeping the meaning unchanged.
Restatement in your own language: When quoting a document, you can restate it in your own language, which will make the quoted document different from the original, thus reducing the duplicate checking rate.
Use quotation marks: when quoting a document, you can use quotation marks to quote the original text, which can clearly mark the source of the quotation and reduce the duplicate checking rate.
Avoid direct quotation: direct quotation easily leads to high duplicate checking rate. So try to avoid direct quotation and restate it in your own language.
Insert pictures: For some things that can't be expressed in words, you can convert them into pictures and insert them into words to avoid repetition.
Please note that the above methods can not completely ensure that the duplicate checking rate of papers is minimized, but also require the author to write the papers carefully and abide by the citation norms.
