This mainly depends on what your topic and research content are, and how your content is composed and divided. You must have a lot of papers and references at hand, so you can basically know how others divide them. I am engaged in mechanical design. According to my previous master's thesis, I mainly wrote about solar cars. I am divided into six chapters. The first chapter is the introduction, which mainly introduces the research status, main contents and research significance of the subject. The second chapter is the basic knowledge and background of the current class, the third chapter introduces the main work and content of your thesis, the fourth chapter is the verification process, and the fifth chapter is the conclusion and prospect. Finally, what thanks and quotations are exactly the same, and everyone is the same.
