Zone 4 is a common periodical, which is not difficult. No one will doubt that the graded articles are false. If you write your own article, don't worry about it.

The meaning of the first district, the second district, the third district and the fourth district: Q 1 is scientific research, Q2 is engineering practice, Q3 is self-certification, and Q4 is spending money to graduate. The paper in the first area requires not only high innovation, but also strict expression, including whether the organizational structure of the article is reasonable, whether the chart is clear and whether the language is standardized. Most of the reviewers in the first district are big cows in this field, so the requirements will naturally be higher. The second area paper is worse than the first area paper in all aspects, but at least there will be obvious innovation. There is a potential similarity between the papers in 1 zone and zone 2, that is, there should be enough workload and rich experimental content. In fact, this is also a supplement to their innovation requirements, because to prove that a new idea is correct and effective, there must be a lot of experimental results to support it. Compared with the first and second districts, the differences between the third and fourth districts are more obvious. Aside from innovation and workload, some journals in the third and fourth districts have very loose requirements on paper format and typesetting, which makes it easier to achieve their goals.
