The topic depends on the content. The key is that you should decide the content of the paper first, which is the most familiar and informative. It is suggested to download more papers, first look at other people's main research directions and choose the one that suits you. Sometimes, I just draw up a topic, and later I find it difficult to write, which is more troublesome!

Once the topic is selected, it is not allowed to change the topic at will, but you can add an appropriate subtitle or adjust the topic under the guidance of the instructor, but you can't deviate from the writing direction of the original topic. The main title is Song Ti No.3; The subtitle uses the word "Song Ti No.4" and is centered under the main title, with a dash in front of the text.

At present, the college only requires students to write Chinese abstracts, which should be comprehensive and concise. For undergraduate graduation thesis, generally no more than 300 words, mainly including the following contents:

1. Summarize the content and structure of the paper, so that readers can clearly understand the main research content and structure of the paper after reading the abstract.

2. The basic conclusions and research results obtained highlight the new insights and the significance of the conclusions or results.

3. Summarize the research methods of this paper.

4. In order to make the abstract smooth as a whole, the author often mentions the research background and purpose of the thesis in this part, but introducing the research background and purpose in more detail should be the problem to be solved in the preface. Therefore, in the abstract, if it is also involved, it should be concise.

Keywords are words or terms directly selected from the paper for document indexing, which are used to express the information items of the full-text theme. Key words should be controlled between 3 and 5, preferably 3.
