摘　　要：根据拟从属关系定义了一类单位圆盘内有关对称点的双单叶解析函数,利用拟从属的性质研究了它们的系数|a_(2)|和|a_(3)|的估计,推广了已有结论,改进了以往的证明技巧.In this paper,a class of bi-univalent analytic functions related to symmetric points within a unit disk are defined based on quasi-subordination relationships.The properties of quasi-subordination are used to study the estimation of their coefficients|a_(2)|and|a_(3)|,which generalizes existing conclusions and improves previous proof techniques.
