The influence of the first and second failure of blind trial.
It doesn't matter. The doctor's blind test is two chances, if. If 1 fails, the second time is very important. If the second time still fails, it means that the doctoral thesis fails, which means that doctoral students have to revise their thesis by delaying graduation for one year. Of course, the probability of delaying the completion of the doctoral program is still quite high, and it will not have any impact after the second time. The blind evaluation system is to send dissertations without the author's name to experts who can't know the author for evaluation, so the score should be the most objective. Colleges and universities in general, especially graduate schools, have relevant regulations on blind examination of papers on a regular basis, and most of them randomly select a certain number of papers for blind examination.
