First of all, graduate students should always pay attention to keeping a certain number of words in the writing process in order to deal with the situation that the number of duplicate words exceeds the limit. When writing a paper, we can take some measures, such as streamlining the nonsense and redundant content in the paper as much as possible and improving the conciseness of writing, so as to save the number of words when checking duplicate.

Secondly, if the number of repeated words in the paper exceeds the prescribed upper limit, graduate students can consider deleting or modifying the repeated content in the paper. By studying the structure and logic of the paper, we can find similar paragraphs or sentences, delete or adjust them reasonably, and reduce the repetition in the results.

In addition, if graduate students are worried that deleting too much will affect the logic and conclusion of the paper, they can consider rewriting some repeated paragraphs. By adjusting the language expression, changing synonyms or adding new analytical viewpoints, the repeated content can become more unique, thus reducing the similarity in the repeated inspection results.

Finally, graduate students can also consider using other functions provided by the duplicate checking system, such as setting a certain proportion of citations and references, or changing the number of words in the duplicate checking results by changing words between paragraphs.

To sum up, when the number of repeated words exceeds the prescribed upper limit, graduate students can deal with it by reasonably reducing and rewriting the repeated content. At the same time, we should always pay attention to the reserved text margins and use the functions of the duplicate checking system reasonably to ensure that the papers meet the requirements in the process of duplicate checking. The most important thing is to treat academic research with honesty and trustworthiness, abide by academic norms, and ensure the originality and academic integrity of the paper.
