The first-level title refers to the title with serial number one by one, which is also the largest title. It is in bold type No.4, with single line and no punctuation.

The main purpose of setting the subtitle is to clearly show the level of the article. Some use words, which generally express the central content of this level; Some also use numbers, which only indicate the order of "one, two, three", and play the role of connecting the preceding with the following. It should be noted that no matter which form is adopted, it is closely related to the content of the hierarchy and the close relationship between the upper and lower levels.

Several points of the title of the paper.

1. Don't pretend to be empty. This is also a common mistake that students make when choosing the topic of their thesis. The graduation thesis is mainly a detailed study of a specific field of a certain major. If students choose a wide range, it is difficult to make a detailed analysis of the research field.

2. Add a subtitle. If a main title does not fully represent the views of all articles, you can add a subtitle to explain the main title in more detail. Generally speaking, undergraduate graduation thesis is usually based on specific subjects, which is also conducive to students' understanding.

3. The length is appropriate. If the title is too short, it is difficult to express the exact meaning of the text in detail. If the topic is too long, it will make people lose their patience in reading. Therefore, the number of words in the title is generally controlled at about 20-35 words, so that the content of the text can be fully expressed without being lengthy.

4. Take more titles. If students waver in the process of multiple-choice questions. Then you can list them one by one, and then make a choice according to what you have learned in your own text.
