摘　　要：Obradovic引入研究了非Bazilevic函数并讨论了它的解析性质,受到数学工作者的广泛关注.利用非Bazilevic函数定义了两类新的双单叶函数族,结合正实部解析函数的系数估计和微分从属理论,得到这些函数族的起始项a2和a3的系数估计,所得结果推广了一些已有的结论.The class of non-Bazilevic functions was introduced and studied by obradovic and has attracted many researchers＇ interest. In the present paper, we introduced and investiga- ted two subclasses of bi-univalent functions with non-Bazilevic type. For functions belonging to these subclasses, we obtained estimates for the initial coefficients a2 and a3 by using the coefficient estimates for analytic functions with positive real part and differential subordina- tion. These results generalized some earlier works.
