Regarding the topic selection, the tutor decided to do some research and sum up the problem.

1. Choose to be in line with international standards

If you want to publish articles in international core journals, you must be clear about the current hot trends of international research and choose research topics that are in tune with the international community. At home, due to various factors, there is still a big gap between China's scientific research topics and the international advanced level. Not long ago, an authoritative scientific research institution in China selected some domestic frontier research topics and prepared to participate in international cooperation. However, after arriving in the United States, it was discovered that two-thirds of the topics were no longer in the frontier field, and few people studied them in the United States. In colleges and universities, some teachers have a solid foundation and rigorous scholarship, but their scientific research achievements are not outstanding. The important reason is that they don't understand the dynamics of related academic fields and can't choose a suitable topic.

2. Development of disciplines

For high-level papers, the development performance and sustainable output of the subject play an important role. Fan of China University of Science and Technology found a new way, developed the symbolic method of quantum theory laid by Nobel Prize winner Dirac, and systematically established the "integral theory in ordered operators". From 65438 to 0998, SCI collected 24 papers. His explanation for the high yield of his thesis is that the research is "groundbreaking, and after the breakthrough, it can develop in depth, making the research work self-contained and comprehensive." Yang Xinmin is the teacher who has collected the most papers in SCI, engaged in the research of convexity theory, which rose in 1970s and reached its peak in 1990s. As a new research field, the research theory itself has a lot to study.

When choosing a topic, we must correctly and properly choose the topic and understand the principle of choosing the topic, so as to choose a successful topic that has both academic value and is in line with our own interests, suitable for our own research direction.
