the following items need to be prepared: < br > 1. Paper revision: This is a very important task. Judging from the dissertations I contacted, most of them were completed in a hurry, and there were many problems, large and small. The thesis defense will be reviewed by peer experts and asked by experts, almost all of which need further revision and improvement. The problems of the paper include the accuracy of language expression, the writing standard of the paper, the results chart, the understanding of relevant theories and theories in academic fields and so on. This is also the last chance for graduate students to revise and improve their papers. Once archived, there is no chance to modify it, and errors will always exist. Therefore, the revision of the thesis after defense deserves every graduate student's attention. < br > 2。 Complement and perfection of professional knowledge (make a perfect plan). An important aspect of graduate students' graduation is that the professional theoretical knowledge structure has been improved and improved, which is also a very important guarantee to broaden their thinking. Judging from the defense in recent years, the lack of professional knowledge is a common problem for graduate students. There are some very important professional knowledge that students are not familiar with or even know. Another important aspect of postgraduate graduation is the specialization of knowledge. Graduate students know their lack of knowledge through thesis writing and defense, so they should make up and enrich a plan as soon as possible, strive to be professional and leave no regrets. < br > 3。 New work plan. Graduate students do not have much time to seriously think about their future development in the process of completing their dissertations. After the process of writing a thesis, many exchanges with the tutor and the experts of the defense Committee, I sometimes feel suddenly enlightened and have a clearer understanding of my future academic development and scientific research direction. This is a good time to set new development goals. We should seize this opportunity, seriously think and sort out, and prepare for a new departure.
