摘　　要：利用微分从属定义一类亚纯函数的子类,讨论该函数类与亚纯近于凸函数的关系,得到该函数类的系数估计、卷积性质等,所得结果推广一些已有的结论.A subclass of meromorphic functions is defined with differential subordination and the relationship of this category of functions to be close-to-convex meromorphic functions is discussed.The properties such as coefficient estimates and convolution of this family of functions are obtained.The result obtained has generalized some conclusions available.
