摘　　要：主要研究亚纯函数的导数分担公共小函数的问题,对于两个亚纯函数的阶导数在涉及截断分担一个公共小函数的情况进行了详细讨论,将韩俊峰等人研究的亚纯函数导函数分担值的问题改进为分担公共小函数,得到了导函数的唯一性结论。Meromorphic functions and their derivative sharing of the common small function,i.e.two derivatives of meromorphic function on the truncated sharing of a small function,were discussed in detail.By proceeding from the problem of sharing the value of the derivative of meromorphic function studied by Han Junfeng et al.to the problem of sharing the common small function,the conclusion of the uniqueness of the derivative was reached.
