摘要：

In this paper, we study the uniqueness of meromorphic functions that share two small functions with their derivatives. We prove the following result: Let f be a nonconstant meromorphic function such that (lim(r ->infinity)) over bar (N) over bar (r, f)/T (r, f) < 3/128, and let a, b be two distinct small functions of f with a not equivalent to infinity and b not equivalent to infinity. If f and f' share a and b IM, then f equivalent to f'.
