[Progress in research of quantification of biological age].

Biological age has been proved to be better than chronological age to measure the real difference of aging among individuals, but no consensus has been reached in the quantification of biological age in the field of aging research. In this paper, we summarize some commonly used quantification methods of biological age and discuss the its future development.生物学年龄已被证明优于时序年龄衡量个体间衰老的真实差异，但生物学年龄的量化方法在衰老研究领域至今未达成共识。本文对目前常用的一些生物学年龄的量化方法进行概述，并提出展望。.
