Opening a topic refers to a paper that researchers must elaborate and explain the research problems, objectives, research methods and expected results before conducting a research. This is a planned research plan. The main purpose of opening the topic is to clarify the objectives and contents of the research, the importance and value of the research, and implement all the work in the research plan.

The research of opening a topic can be divided into three stages: the stage of asking questions, the stage of analyzing questions and the stage of planning schemes. In the stage of asking questions, researchers need to find a topic worthy of discussion and clarify the problems to be solved; In the problem analysis stage, researchers need to conduct in-depth research and analysis on the selected problems; In the scheme planning stage, researchers need to make clear the purpose and method of research and determine the specific research scheme.

Opening the topic is a very important work, which is of great significance to the smooth progress of the follow-up research. For researchers, opening the subject can help them to define the research objectives and direction, standardize research behavior, implement research plans and improve research efficiency. For scientific research institutions and academic circles, open topics can help them choose valuable and practical research topics and promote the progress and development of scientific research. Therefore, the research of opening a topic is of great significance, which determines the research results of the whole topic.
