Thesis, which means talking and exchanging ideas in classical literature, now refers to articles that conduct research in various academic fields and describe academic research results. A paper generally consists of title, author, abstract, key words, text, references and appendix. It is not only a means to discuss problems in academic research, but also a tool to describe academic research results in academic exchanges.
In order to achieve the purpose of clear hierarchy and clear context, the text is often divided into several large paragraphs. These paragraphs are called logical segments, and a logical segment can contain several small logical segments, and a small logical segment can contain one or several natural segments, so that the text forms several levels. The level of the paper should not be too much, generally not more than five levels.
