1. Research background and importance.

The first paragraph of the introduction needs to give the background and importance of the research field. This background outlines a trend or trend of scientific research achievements in this field from ancient times to the present, which provides a hotbed for the development and growth of this paper. The development of this part of the content must quote the classic literature or basic works of predecessors and Daniel in this field, indicating that your overall grasp of the subject is comprehensive and objective. So how to introduce this background into the title of the paper? When we gradually narrow the scope from the general trend of this academic field, we only need to mention "only stick to relevant information" to ensure a natural transition to the scientific research topic to be discussed in this paper.

2. Draw something unknown in this field.

After introducing the general situation of this research field, it is logical to point out which fields (or problems that have not been thoroughly studied) we have not covered yet. Of course, there are thousands of such problems in Qian Qian, so I can't list them all here. It is necessary to talk about them according to the topic of your thesis. To put it bluntly, it is what you wrote in your paper. Here I write "This topic has not been touched by many researchers" and so on.

3. Point out the theme of the research paper.

Since the research blank is close at hand, the corresponding research topics should follow closely. Next is the moment when you confidently state the theme of this paper. At this time, you need to pay attention to the echo of the research gap, that is, go further on the basis of what the topic is and briefly analyze how this topic fills the research gap.
