First of all, we need to be clear about the reasons for code duplication. The code duplication in this paper is mainly due to the following aspects: first, the lack of full understanding of the existing research leads to the lack of in-depth understanding of the code of similar research, which leads to code duplication; Second, when writing a thesis, I failed to make full use of the existing code for innovation, and simply copied and pasted the existing code, resulting in code duplication; Thirdly, the author's management of code reuse is unscientific and lacks reasonable organization and norms, which leads to excessive code repetition.

First of all, the author of the paper should strengthen the full understanding of the existing research, know as much as possible the code content and ideas of similar research, and avoid reusing similar codes. Secondly, the author should think creatively when writing the paper, and make secondary development and improvement by understanding and absorbing the existing code and combining his own research content to avoid simple copying and pasting behavior. Finally, the author needs to organize and standardize the code reasonably and establish a scientific code management mechanism to avoid code duplication.

At the same time, the duplicate checking system is also an important way to solve the problem of code duplication in the paper. The author of the paper can use the duplicate checking system to check the duplicate of his own paper, and find and modify the code duplication in the paper in time. In addition, for thesis tutors and review experts, it is also possible to detect the papers submitted by students through the duplicate checking system, find and guide students to solve the problem of code duplication in time, and improve the quality and level of academic literature.

To sum up, the problem of code duplication in this paper is a challenge facing the current academic circles. In order to avoid code duplication, the author of this paper needs to strengthen the understanding of existing research, think creatively and establish a scientific code management mechanism.
