The number of papers published in mathematics increased sharply from 20 19, from less than 400 papers a year before, to 1234 in 20 19. So far this year (9. 16), mathematics has published 13 18 articles.

Although the influencing factor of mathematics is only 1.747, it is in the field of mathematics. JCR zone 1. The efficiency of editing and reviewing manuscripts is very high, and the review and employment are relatively fast. This paper is about the mathematical deduction and analysis of the theoretical model of mechanical dynamics, and has recommended many foreign commentators in related fields.

The three reviewers gave their own opinions, all of which were to the point and really understood the complex dynamic mathematical model and research content. One of the reviewers even deduced the full-text formula himself and pointed out the shortcomings. A round of overhaul and a round of minor repairs, revised and improved the paper, and was quickly hired.
