There are many cases in which the master's thesis fails the blind examination. The following are some common situations: \r\n 1. Poor paper quality: unclear language expression, chaotic structure and improper research methods may lead to poor paper quality and failure to pass blind inspection. \r\n\r\n2。 Unclear research questions: if the research questions are not clear enough or the research objects are not specific enough, it will leave a vague and uncertain impression on the evaluation experts, thus affecting the evaluation of the paper. \r\n\r\n3. Improper data processing: Improper data processing, incorrect analysis methods or unreliable data results may lead to the paper being rated as unqualified. \r\n\r\n4。 Academic norms: academic misconduct, such as plagiarism and forgery. It will lead to the failure of blind evaluation of papers. \r\n\r\n5。 The experts' opinions are strict: the experts have high requirements for the paper and put forward many suggestions for revision, but the author fails to make the revision according to the opinions or the revision is insufficient, which may also lead to the paper failing to pass the blind evaluation. \r\n\r\n6。 Inconsistent with the research field: the research field of the paper is inconsistent with the research direction of the judging experts, or the content of the paper has nothing to do with the research hotspot, which may also lead to the failure of blind evaluation. \ r \ n \ r \ nIn short, in the process of writing, we need to take every link seriously, pay attention to the quality and academic level of the thesis, fully understand the requirements of the school and the tutor, and strictly abide by the academic norms and writing norms, so as to better pass the blind inspection of the master's thesis.
