1. The paper needs to be checked twice, but since it is a random check, the number of people checking copies will not cover everyone. The sampling number of bachelor, master and doctor is 1%, 5% and 10%, respectively. When sampling, the sampled paper will be checked twice. If the results are unqualified, even if you get an integer after graduation, the degree certificate of the unqualified thesis will be seriously cancelled.

2. First of all, we should know that the appendices of a paper are generally repetitive, and the paper duplication checking system will detect the uploaded content, and most of the appendices come from the network, that is, in the case of non-originality, the possibility of appendixes being marked red will increase; At this time, the repetition rate of the whole paper will be affected.

3. In addition, the appendix format also needs to be strictly controlled. If the appendix format is incorrect, the paper duplicate checking system will default to the main part of the paper. At this time, the repetition rate of the paper can also be improved.

4. If the university does not require to check the appendix of the paper, it can choose not to upload the appendix when checking the paper, so that the final repetition rate of the paper will not be affected.
