First of all, we need to understand the principle and purpose of paper duplicate checking. Paper duplication checking system can detect plagiarism and repetition in papers by comparing existing documents with relevant information on the Internet, thus ensuring the originality and academic integrity of academic research. Secondly, we should pay attention to the citation of literature and the compilation of literature review. Reasonably quoting other people's research results can improve the academic value of graduation thesis and reduce duplication. In addition, a well-written literature review can also show the comprehensiveness and depth of the research. At the same time, it is also very important to avoid copying and pasting other people's words directly in the process of writing a thesis. Although it is ok to refer to other people's opinions and achievements in writing, it needs to be integrated and summarized through your own understanding and expression to reflect your research ability and thinking ability.

In addition, we should pay attention to the structure and language expression of the paper. A clear and coherent paper structure can not only make readers understand the content of the paper more easily, but also reduce the misjudgment of the duplicate checking system. In terms of language expression, it is necessary to avoid using complex sentence structures and expressions with too many terms and avoid unnecessary repetition. At the same time, the rational use of quotation marks and quotation formats can also improve the academic standardization of the paper and reduce the detection results of the duplicate checking system.

Finally, we need to use some special tools and software to check the duplicate of the paper. There are many duplicate checking systems and tools on the market now.
