Peer review is a necessary process for the publication of papers, which is determined by the characteristics of scientific papers. Peer review is to accept peer evaluation, which mainly evaluates whether the paper has publication value from the aspects of innovation and science.

In the preliminary examination of editors, editors conduct preliminary examination and evaluation of papers and manuscripts in charge of majors or disciplines, so as to decide whether to reject manuscripts, drop out of classes or send them to experts for review.

After the paper passes the preliminary examination, the editor will also send the paper to peer review, and generally invite two or three reviewers to review it. Most of the judges are experts and well-known scholars in the forefront of scientific research in this field. Generally speaking, the greater the influence of journals, the higher the academic level of selected reviewers. Then according to the content of the paper, the opinions and suggestions of minor repair/overhaul/scrapping are given; But this process takes the longest time, usually 3- 12 months.
