The rule of duplicate checking is to judge whether there is plagiarism or plagiarism by comparing the similarity between the paper and other documents. Specifically, the paper duplicate checking system will judge the similarity according to the following rules:

If 13 consecutive characters are similar to other test papers, the duplicate checking rate is calculated.

If you extract a long text or other article word for word, even if you only change a few words or the corresponding words, it will be regarded as plagiarism.

Table text will also be repeated. If the content is basically similar to others', it will lead to a high repetition rate.

Quoting other people's literature will also be regarded as plagiarism if it is incorrectly marked.

When quoting and referring to other people's literature, we must pay attention to the number of words used. If the number of words exceeds the prescribed threshold, it will also be regarded as plagiarism.

It should be noted that the duplicate checking rules and algorithms of different paper duplicate checking systems may be slightly different, and the specific duplicate checking rules and algorithms depend on the duplicate checking system used. At the same time, in order to protect academic integrity and intellectual property rights, it is suggested to consciously check the duplicate before submitting the paper to ensure the originality and academic integrity of the paper.
