In addition to the above requirements, the review of the repetition rate of doctoral dissertations is also very strict. In fact, duplicate checking is to detect the repetition rate of papers, that is, to see whether academic misconduct such as plagiarism is serious, standardize the writing of papers, and improve the originality of papers.

The repetition rate of doctoral dissertations is much stricter than that of undergraduate master dissertations. The repetition rate of undergraduate dissertations is generally within 30%, that of master dissertations is generally within 15%, and that of doctoral dissertations is generally within 5%.

Although most colleges and universities have certain differences in the standards for doctoral dissertations, they are all very strict. Everyone should carefully write their doctoral thesis according to the specific regulations of their own school.
