The third area of SCI refers to the periodical area where the impact factors are in the middle and lower level.

The quantity and quality of periodicals in the three fields of SCI are different in different disciplines, so the level of division will be different. In some disciplines, SCI journals are the main publishing channels, such as journals with low impact factors in emerging disciplines. For researchers, SCI three-zone papers play an important role in improving their academic status and influence, and are also one of the important bases for applying for scientific research projects, obtaining degrees and awards.

It should be noted, however, that the journals in SCI area three have very high requirements on the quality of papers, and the review process of papers is also strict, so it is difficult to publish them, which requires researchers to have high academic level and research ability.

In addition, journals in SCI Region III also have specific research directions and fields. For example, some journals mainly publish papers on a specific subject, such as chemistry, biology and medicine. Therefore, journals in the three fields of SCI also have specific research fields and audience groups, and their values and functions are different for researchers in different fields.

It takes some experience and strength to publish papers in SCI-III journals, so it is relatively difficult for new researchers to publish papers in SCI-III journals. In addition, publishing papers in journals in three regions of SCI also needs some financial support, because a lot of experiments and research work are needed.

In a word, SCI-3 periodical is an influential and recognized periodical in academic circles. For researchers, the papers published in these journals have important academic value and practical significance. However, it needs some strength and experience to be published in the high-quality journals of SCI III.
