First of all, the defense should be clear about what graduate students should be examined in the thesis defense. Master education focuses on cultivating scientific thinking, how to carry out scientific experiments, how to turn scientific achievements into academic articles, and even create social benefits. Doctoral education focuses on cultivating graduate students' creative thinking, striving to make a breakthrough on the basis of previous studies, and requires doctoral students to have good and new scientific research ideas during their study. By clarifying the above, we can know the central issues that the experts of the National Defense Commission are concerned about.

(A) review the authenticity of the paper

The authenticity of the paper includes whether the basis of the topic is completely feasible (generally there is no problem, otherwise it will not be passed when the project report is opened, and of course experts may question it, which requires a full understanding of the research background and basis); Whether the experimental design is scientific and reasonable; Whether the experimental steps and operation methods are accurate; Whether the statistical methods are properly applied and whether the data analysis results are credible (SPSS or SAS software is generally used for statistics. Non-statistical professionals had better consult statistical professionals in medical colleges or ask teachers for help when sorting out and calculating data to ensure the accuracy of statistical methods. This is very important, because improper use of statistical methods may lead to changes in statistical results, which may lead to invalid conclusions).

Seeking truth from facts is the basis of scientific research, and the paper itself must be true and reliable, and fraud can not escape the attention of experts in the defense Committee. If there is a problem in this respect, the paper is bound to fail to pass the expert review.

(two) to investigate the relevant knowledge and application ability.

Graduate students should be familiar with and master the professional knowledge and related basic knowledge in this field. A complete and reasonable scientific experiment generally involves? PRFR？ The following sections:

( 1)? Former? Previous successful experiments. In other words, the project has a foundation and cannot be virtual. The research paper is a scientific hypothesis based on predecessors, so be careful to verify it.

(2)? Repeat? Repeatability. It not only covers the repetition of the previous experiments, but also ensures that the experiments of the respondents can be repeated later. The experiments that can be repeated can prove to be high-level research and credible research.

(3)? Fresh? Innovation. This is the soul of a nation and also the soul of a scientific experiment. Without innovation, science will not progress. Although repetition is very important, freshness is based on repetition, which is more scientific and popularized.

(4)? Reliability? Reasonable and reliable scientific conclusions are the ultimate goal of researchers.

(C) to examine the comprehensive quality of graduate students

Including the respondent's expressive ability (for example, the defense Committee asked to explain how an experiment mentioned in the paper was operated, and what did you learn? ), adaptability (for example, a defense, the judges ask questions:? Please summarize your tutor in one paragraph? How sharp is it? It has nothing to do with professional knowledge, but it is closely related to the respondents.
