SCI refers to the scientific citation index, which is one of the largest academic citation databases in the world. SCI journals are authoritative academic journals in the world, and the number of SCI journals is the only identification symbol when cited. SCI serial number is widely used, which is not only an important reference index for academic researchers to publish papers, but also an important basis for researchers to evaluate academic influence, SCI periodical evaluation index and university scientific research grade evaluation.

The serial number of SCI is an important part of influencing factors and one of the important indicators of SCI journals. The impact factor describes the average citation frequency of the journal this year and reflects the quality and quantity of articles published in the journal. The higher the number of SCI issues, the higher the impact factor, indicating that the more recognized and concerned by the academic community, the greater the academic influence. Therefore, the serial number of SCI is of great significance to academic circles and researchers, which can help them to better refer to and use academic resources in academic exchanges and scientific research and improve their academic level.

SCI periodicals and SCI issue numbers are of great significance to researchers and academics. However, the serial number of SCI is not the only evaluation index. The quality and academic level of academic papers need to be comprehensively evaluated by other indicators. In addition to SCI journals, there are also important indicators such as English core journals, Chinese core journals and impact factors. In scientific research and academic exchanges, we should comprehensively consider different indicators and evaluate and utilize academic resources more comprehensively.
