Now the second area of SCI is that many authors will choose to publish their papers. Many colleges and universities require journals of the second area and above, but it is more difficult to publish journals in the first area, so the second area has become the first choice for everyone. What is the general value of the impact factor of the second area of sci? Next, I will let you know about it.

The impact factor of the second area of sci is generally between 0.5-1.5. The division of sci is divided according to the impact factor, the first 5% is the first zone, the first 20% is the second zone, the first 50% is the third zone, and the rest is the fourth zone.

How to properly look at the sci partition?

The impact factor is an internationally accepted journal evaluation index. Generally speaking, the higher the impact factor, the greater the impact of the journal. The sci journals also follow this principle, so they are divided, that is, the JCR division formulated by Thomson Reuters and the SCl division of the Chinese Academy of Sciences, both of which are divided based on the impact factor of the journals included in sci.

Chinese Academy of Sciences SCl division: The Chinese Academy of Sciences sci division is divided according to the journal's three-year average impact factor; the first area: the first 5%; the second area: 6%~20%; the third area: 21%~50%; the fourth area: the last 50%;

JCR division: It is to arrange the impact factors of all journals in a certain discipline in descending order, and then divide them into four areas. The proportion of each area is equal, both of which are 25%.

In fact, there is no absolute which is more reliable between JCR and Chinese Academy of Sciences in the sci division. In fact, both division methods are more authoritative and are only used for reference. How to look at it, the most direct method is to see which one your school/unit recognizes.

Impact factor score: The score of CI also becomes the IF score, IF = the number of citations in the first two years / the number of articles included in the first two years, sci journals generally include more science and engineering, taking chemistry professional journals as an example, IF is less than 3 is very general, 5 or so is an excellent journal for small majors, 10 or so is a very good journal, and more than 10 is generally a review journal.

After the manuscript is finalized, the journal will be selected. The impact factor of general journals does not change much. Authors need to pay attention to the latest SCI journal catalogue. The journal catalogue of SCI is the same as that of domestic core journals. It is not static and will be updated regularly. Publications that do not meet the requirements will be removed from the catalog, so authors must filter publications from the latest catalog.

After the journal is selected, the manuscript is submitted. The SCI submission is generally a systematic submission. The databases such as Elsevier, Springer, and Wiley all adopt the online submission mode, so the contributors need to have some understanding of the submission system. The use of the system is similar, and the author uses a few more It can be mastered at once, and a series of processes and links such as the review of subsequent articles can be queried through the system, which is also very convenient
