innovative, accurate and feasible. 1. Value: it means that the selected topic should have certain research value, that is, what is the significance of the expected results of this research to teaching practice. Innovation: it means that the selected topic should be innovative, mainly reflected in a sense of the times, new ideas, new contents and new angles; 3. Accuracy: it means that the topic should be defined accurately, and the topic that you can control should be identified; 4. Feasibility: It means that the selected topic is operable, and the researcher has the subjective and objective conditions to master the topic. He has basically mastered the writing method of the topic declaration. First, writing must be positioned: the content and scope of the subject research is not that the more you write, the bigger the better. You must be good at grasping the key points and grasping the depth of the research content and its relationship with your own conditions and abilities. The formation and selection of a subject is a difficult stage in scientific research. Choosing a subject is to correctly position one's main attack direction, and understanding that correct positioning is half the success of applying for a subject. Second, research before writing: research before writing is very important to avoid low-level repetition. Therefore, first of all, we should closely contact with the competent department of science and technology, and keep abreast of the situation of national and local scientific research funds and the service direction of our own scientific research; Secondly, we must strengthen the literature review and investigation before the declaration, keep abreast of the technical status, dynamic trends and existing problems in this research field at home and abroad, and carefully analyze them to determine the main direction and goal according to our own advantages; Thirdly, the applicant should understand the nature, characteristics, funding methods, funding intensity and targets of scientific research projects in various channels, so as to choose the corresponding projects that suit his own characteristics. Third, we should work hard on new words: the project declaration highlights the novelty of our research content, and through retrieval, we can know whether the relevant scientific research project has been done, the degree of research, and whether there are any literature reports closely related to the subject. If there are closely related literature reports, we should try our best to find the original literature and find out the differences between the research ideas, project design, research methods, technical means and experimental materials, as well as whether my research methods and technical means are more reasonable and scientific, and whether the social and economic benefits are greater. At the same time, in some aspects such as project objectives, research ideas, content design, research methods, technical routes or technical means, and technical achievements, others have not done or obtained. Fourth, we should pay continuous attention: any topic within the scope of the topic guide is a blank spot in cutting-edge scientific research that all disciplines pay more attention to, which is continuous and requires bidding every year. If we don't care about the success or failure of the temporary application, determine the research objectives and make persistent exploration, I believe we will succeed in the application one day. I have a rough understanding of the writing skills and requirements of the subject declaration, and understand that the title of the subject should intuitively reflect the content to be studied, and the content should be objective, and the key content or technology should not be vague, so as not to cause misunderstanding. Don't just talk about advantages, talk less or not talk about disadvantages, and choose the appropriate research depth depending on the level of the subject to be declared. I understand that there are certain requirements for the number of words in the project name in the project declaration. Probably know that the members of the research group should be an echelon combination, with both senior titles and middle-and low-level titles, and it is best for graduate students of various related majors to have them, because many outstanding achievements are obtained by interdisciplinary research, and the acquisition of innovative achievements generally requires teamwork, so the personnel structure should be reasonable. A clear understanding of the correct research methods and technical routes is the key to success. After determining the theme and purpose of scientific research, it is an important content in the early stage of scientific research to formulate correct research methods and technical routes. Research methods and technical routes are research schemes and technical measures designed to complete the research content, including theoretical analysis, experimental methods, work steps and a whole set of planning arrangements. Know that you should pay attention to careful design, scientific method, reasonable route, advanced and feasible technology, specific and clear measures, and avoid ambiguity and ambiguity. At the same time, I understand that it is necessary to have a certain pre-experimental basis and fully display the previous scientific research results of the project leader and participating members related to this project. Anyway,
