摘　　要：研究亚纯函数的导数分担公共小函数的情形,通过限制其亏量与精简分量,得到导数分担一个小函数的亚纯函数的惟一性.This paper mainly studies the case that the derivatives of meromorphic functions share a common small function.By limiting its deficit and simplifying components,the uniqueness of a meromorphic function with its derivatives sharing a small function is obtained.

关 键 词：亚纯函数 公共小函数 惟一性
