中文摘要：

在h指数启发下发现一个新的学术排序指数——f指数，该指数与学科相关，综合了数量与质量因素，普适于学科、国家、机构、期刊、学者多层面学术排序，其计算公式为： f=（100×HCP/P）×（100×C/TFC）=CPP×HCP/TFC×10^4≥0 其中P，C，HCP分别为论文、引文和高引论文数，TFC是相关学科的总引文数，CPP：C／P是平均引文。22个学科、18个国家、18所大学、10种期刊和10名学者的／指数被具体测算。实算数据表明厂指数值处于0～100之间，f≥1表征优秀。

英文摘要：

Inspired by the h-index, this author finds a new index called the f-index based on the ISI-ESI database, for academic comparisons at the field, country, university, journal, and author levels. The index can be calculated according to the formula ： f =（100 ×HCP/P ）×（100 × C/TFC）=CPP × HCP/TFC× 10^4 ≥ 0 where P, C, HCP are respectively Papers, Citations, Highly Cited Papers of a field, a country, a university, a journal, or a scientist in ISI-ESI database; TFC stands for Total Field Citations concerning relative fields; and CPP denotes citations per paper. 22 fields, 18 countries, 18 universities, 10 academic journals, and 10 famous scientists are chosen for practical measurement of the f-index. Real data show that a larger f indicates better academic researches and f-index values fall within 0 - 100.The f- index seems a good all-round index combining quantitative productivity with qualitative impact together and f ≥ 1 indicates excellence.
