Hello: You must write an abstract for your master's thesis, whether it is a big thesis or a small one to be published after graduation. Because the function of the abstract is to help readers quickly obtain whether the paper is helpful to them, it can be condensed into an abstract through full text extraction for readers to use. Therefore, the abstract is the abstract of the paper, which should include all the contents, not just the experimental part. Briefly describe the research background, purpose and significance, especially put forward the problems to be solved, and then focus on your own research achievements and innovations, preferably clear specific values.
