The Institute of Scientific information has edited an index to evaluate the diffusion of scientific articles. It is based on the fact that the more an article is cited as a reference in other articles, the more it is considered to be important, and the higher the coefficient attributed to the journal in which it was originally published. The impact factor takes into account the average number of times which a journal is mentioned for recent articles published in a given year. This index is an attempt to quantify the notoriety of scientific journal for all scientific medical specialties.
科学信息研究所编辑了一个索引来评估科学文章的传播情况。它基于这样一个事实：一篇文章在其他文章中被引用作为参考文献的次数越多，就越被认为是重要的，并且其最初发表的期刊所获得的系数就越高。影响因子考虑了某一特定年份发表的近期文章中某期刊被提及的平均次数。这个索引试图量化所有医学专业领域中科学期刊的知名度。
