Under normal circumstances, a small paper should be part of a big paper. However, in actual research, the research content of small papers does not necessarily belong to big papers. Therefore, small papers and big papers overlap, so it is enough to compare and correspond, and it is not necessary to correspond completely.

The function of publishing small papers:

1. Small papers may be required by graduate students. Many universities require graduate students to publish papers, provincial or national, and some even require the publication of core journals of Peking University. The specific publishing requirements depend on their respective colleges and majors.

2. This paper is a bonus for evaluating scholarships. Although graduate students may not get a scholarship for publishing their papers, because the papers are only extra points, not decisive, but they can get extra points for publishing their papers. Although the proportion is not large, many students may not get scholarships by two or three points every year, so they will generally pay them.

3. Small papers are helpful for finding jobs and evaluating professional titles. After graduation, papers are usually of little help in finding a job. But for example, when you are a teacher and enter a graduate school and other work units that pay attention to knowledge research, then the thesis is a stepping stone. Ordinary papers are of little value, but some core, EI, SCI and advanced papers will play a greater role in finding jobs and evaluating professional titles.
