Blind trial is also called anonymous trial. As the name implies, this thesis evaluation system is that the school anonymously sends the graduation thesis written by its own students to experts from other schools for evaluation, so the experts who participate in the evaluation will not know who the author is. Of course, the students who are judged will not know who the experts are when judging their papers. The blind examination system is adopted to ensure the objectivity and authenticity of the evaluation results on the one hand, and to ensure the fairness and integrity of academics on the other. The evaluation results of papers are not affected by other factors under the condition that both parties participating in the evaluation are anonymous, and can truly reflect the true academic, scientific research and writing level of the papers. The reason why the blind exam is important is that only students who pass the blind exam have the opportunity to participate in the graduation thesis defense, and only after the defense is passed can they successfully obtain their degree certificates and graduate smoothly. If students fail in the blind examination of their papers, they will only face the dilemma of delaying graduation. The school has strict requirements on the number of papers submitted for review and the study time at school. Students need to revise and submit their papers within the specified time, and the pressure on them can be imagined. And if students fail in the final blind test, the school will not issue them with a degree certificate.
