Many people think that the repetition rate of undergraduate thesis will be zero, and the number of words in undergraduate thesis is relatively small, but it generally does not appear. Generally speaking, your character may go beyond the detection range of the detection system when detecting the paper, resulting in the detection system being unable to recognize it. If the detection is not finished, stop the detection, then report the detection failure, and then the repetition rate is zero.
Many students combine several papers to test in order to save money. Because each paper has its own theme, some students may combine papers from different majors for testing. Generally, the test system will automatically detect the test papers in sections. If several test papers are combined, it may interfere with the test system, so it will not be detected.
The paper duplicate checking system has a prescribed format, which some students may not understand. If the format is different from that specified by the detection system, the natural detection system will not detect it. The general detection system requires students to use word files when uploading papers, because the pdf format may not be recognized, so the detection result of incorrect format is zero.
