The R- and AR-indices： Complementing the h-index

Based on the foundation laid by the h-index we introduce and study the R- and AR-indices. These new indices eliminate some of the disadvantages of the h-index, especially when they are used in combina-tion with the h-index. The R-index measures the h-core’s citation intensity, while AR goes one step further and takes the age of publications into account. This allows for an index that can actually in-crease and decrease over time. We propose the pair (h, AR) as a meaningful indicator for research evaluation. We further prove a relation characterizing the h-index in the power law model.     

Hirsch 指数研究的新进展

提出了离散Hirsch 指数（简称h 指数）的精确定义，引入了“Hirsch 核心”这一概念。不仅将h 指数推广到实数集，还介绍了其他相关的派生指数，g 指数和A 指数。只有h 指数和g 指数相结合，才能较全面地评价科学家的科研成就。
