(1) The topic of the thesis mainly depends on whether it belongs to the frontier of this discipline and whether the research work has theoretical significance and practical value. In China, most of the projects listed in the National 973 Project Plan, the 863 Project, the National Natural Science Foundation and the National Key Scientific and Technological Projects are at the forefront of scientific development, because they have been demonstrated by peer experts in the process of project establishment, which is the focus or focus of peer attention.

(2) Literature review mainly depends on whether we have mastered the latest trends and progress of related research work in this discipline. Literature review has two aspects: quantity and quality. In terms of quantity, it mainly depends on whether the main documents related to this subject field are basically covered around the theme of the paper, and in terms of quality, it mainly depends on whether the representative papers and influential main documents in this subject field are summarized. For example, the literature of influential academic journals and conferences in this discipline and the works of influential scholars should be reflected in the literature review. More importantly, the dissertation review needs to be summarized by the author's literature review to see if it summarizes the overall trend, law and problems to be solved in this discipline and research direction.

(3) Main work and innovation, academic significance and value, which are the core contents of dissertation evaluation. For doctoral dissertations, the research work should be innovative and systematic. Comments should not only list, summarize and summarize the main work and innovations of the submitted review papers, but also point out their academic value.

In the writing of dissertation comments, a prominent problem is that in the reviewed graduate dissertations, the general author has summarized the main work and innovations of the dissertations, and the reviewers of the dissertations should summarize and evaluate the work and innovations of the dissertations from a higher height and a broader perspective.

(4) Thesis writing Thesis writing is an important aspect of dissertation evaluation. It mainly examines whether the writing of the paper is clear and coherent, whether the experimental data is reliable and whether the inference is scientific and correct. Through the writing of the paper, we can also see whether the author has a meticulous work style, and the orderliness and systematicness of the paper are also the embodiment of whether the research work is systematic.
