Graduate students mainly attend classes in the first academic year, and generally enter the project work of the research group in the second academic year. Depending on what kind of project team you follow, you help teachers with more horizontal projects. For one's own study, the first thing is, of course, to complete the task given by the teacher. Completing the teacher's task with good quality and quantity is the first priority, and then you can read some related documents. For a graduate student, if he wants to engage in scientific research, he will inevitably encounter the contents of other disciplines and need to learn by himself. As for writing a thesis, it's actually very simple. Look at the articles of the lab brothers first, and read more. On the one hand, we can grasp the whole research field of the laboratory, on the other hand, we can look at the structure, content, text and image processing of other people's papers. After mastering these, think of a topic by yourself, and then program (software) to calculate and calculate a case, but remember the relevant analysis. For the paper, it is not only a picture and several formulas, but also the pre-processing and analysis are the most important. The efforts in writing must be strengthened, even the abstract and introduction need great efforts. Good luck with your studies.
