What do you mean by sci?

If the impact factor of sci is greater than 2.0, it is regarded as q2 area.

Choosing journals is the key to publishing sci papers, but sci journals are different from domestic journals. Domestic journals are divided into provincial, national and core levels, and sci journals are also divided into levels. The difference is that sci is divided into periodicals. How to divide sci areas? The division of sci journals is mainly based on the impact factors of journals, but sci has two divisions, so there are two types of division standards.

Sci journals are divided into two parts: China Academy of Sciences and jcr. Let's start with jcr, also known as Thomson Reuters. * * There are four parts: Q 1, Q2, Q3 and Q4. Q 1 is influenced by the first 25% (including 25%), and 25% ~ 50% (including 50%) is Q2.

Let's look at the division of Chinese Academy of Sciences. The Chinese Academy of Sciences also divides sci journals into four regions, with the top 5% of the impact factors being 1 region, 6%-20% being 2 regions, 2 1% -50% being 3 regions and the rest being 4 regions. Generally speaking, the two regions are divided according to the level of influencing factors, but the difference is that the standards in each region are different.

Many authors struggle whether to choose publications according to the division of Chinese Academy of Sciences or jcr. In fact, the two types of division are authoritative, and the choice of which one is appropriate depends on the author's publishing needs and the requirements of schools and units. The department of Chinese Academy of Sciences is the most efficient or scientific research institution in China at present, and the author should make a choice according to the specific requirements. The above is the introduction of sci branch.
