First, the correct topic selection is the core of writing the project application. The correct topic selection determines the central idea of the application, and deviation will affect the feasibility of the whole study. In fact, choosing a topic is to ask questions and assumptions. Nowadays, all kinds of topics emphasize that research problems should come from teaching practice, and finding problems should rely on thinking instead of feeling. At the same time, we should browse a large number of documents according to the questions raised, and the published documents are the scientific basis for the topic selection. The topic should be expressed in words, and the writing of the topic is also very important, so that people can know the research content after reading the topic. The topic should not be too long or too short, but should closely follow the research content and express the central idea. The problem we often encounter is to do small projects under big topics, and there are also big projects under small topics. The size of the topic depends on the content of the study. If you let others look at the topic, you can know what specific research you are writing, what the research object is, what research methods you use and what specific problems you solve. In peer review, it means that you have made the first move, so give full play to the role of the topic. Second, the sufficient basis for the establishment of the topic should include the research significance, research status at home and abroad and analysis. As a basic research, the scientific significance should be discussed in combination with the development trend of scientific research; As an applied research, it is necessary to combine the key scientific and technological problems that need to be solved urgently in national economic and social development to explore its application prospect. Attention should be paid to the following aspects: ① Introduce foreign trends, especially domestic research. (2) The reasons why the applicant is engaged in this research must be clarified. Some applications only talk about the significance and domestic and international trends of this topic, without introducing why the applicant is engaged in this research. You should clearly introduce what you found in your previous work, what problems exist in other people's work, or what special ideas you have on scientific issues, etc. Otherwise, the basis is insufficient. (3) Adhere to the basic national policy of doing something and not doing something, and filling vacancies is not the basis of the project. (4) Many applicants take filling in gaps as the reason for establishing projects, and the purpose of scientific research is to solve problems rather than fill gaps. ⑤ The main references should show the key research work at home and abroad, pay attention to timeliness, and pay special attention to the recently published documents. In short, the purpose of the project should be clear, the reasons for the application should be sufficient, the basis of the project should not be too popular, and the key issues should be clearly explained, so as to arouse the interest of the reviewers and make them willing to continue reading your application, so that the application can be competitive.
