Blind evaluation generally does not check the opening report, because blind evaluation only sends papers. Blind evaluation is to send a dissertation without the author's name to an expert who is impossible to know. This score should be the most objective. Generally, colleges and universities have relevant regulations on blind evaluation of dissertations on a regular basis, and most of them randomly select a certain number of dissertations for blind evaluation (some schools require 100%). Blind trial mainly examines two aspects: first, hard indicators such as word count, duplicate checking and format specification; Second, it includes the summary, analysis, discussion and other important contents of the design results, mainly examining the arguments and innovations. And the paper is the most important, as long as there is no problem with the paper itself, other aspects of the content will not be too concerned.
