Extended data:

A part written in front of a book or an article, similar to a preface or introduction. It also refers to the opening remarks of a forum or discussion. The preface of the paper is also called introduction, which is a short paragraph in front of the text. The preface is the preface of the paper, which aims to explain the ins and outs of this study to readers, arouse readers' interest in this paper, and play a role in outlining and guiding reading interest in this paper.

Before writing the preface, we must first clarify several basic questions: What do you want to explain through this article? What are the new discoveries and whether they have academic value? After reading the preface, the general reader can clearly know why the author chose this topic for research. Therefore, before writing the preface, we should know as much as possible about the relevant contents, collect the main data of predecessors and others' work, and explain the rationality of this study.

Second, the title of the paper requires accurate expression of the content of the paper and appropriate reflection of the scope and depth of the research. Common faults are: too general, the topic is not deducted. The key problem is that the topic should be closely related to the content of the paper, or that the content of the paper should be closely related to the topic, that is, the topic should be deducted and the article should be deducted. This is the basic principle of writing a thesis.
