The opening report of graduation thesis does not participate in duplicate checking, but only plays a guiding role, which has a strong guiding role in the main content and central idea of graduation thesis. Of course, it also played a role in enriching space. The premise of not testing the opening report of undergraduate graduation thesis is that we need to mark it correctly, and at the same time, the paper catalogue and references are not involved in the test. The opening report, table of contents and cited documents of the paper do not involve duplicate checking of the paper, but they are needed in the correct format. Only when the paper format is correct, the detection system will prompt that only the text content will be detected, and the parts that did not participate in the detection will be displayed in gray and the repeated parts will be displayed in red, so that the detection results can be seen very intuitively.
