摘　　要：在复平面C中单位圆盘U上建立了强的α次β型螺形函数和强α次星形函数的增长、掩盖定理与偏差定理的下界估计,所得结果推广了已有的一些结论.Abstract：In this paper, we study the growth,covering theorems, the estimates of lower bounds of dis- tortion theorems for strongly spirallike functions of type β and order a and strongly starlike functions of order a in the unit disk U of complex plane C. Our results generalize some known results .
