摘　　要：研究单位圆盘上的调和映照在一定的规范条件下双积分算子的单叶半径,得到其结论是精确的,并给出其极值函数;之后研究单位圆盘上的调和映照在不同规范条件下双积分算子的单叶半径,得到其结论是渐进精确的.In this paper the single leaf radius of the double integral operator on the unit disk under certain standard conditions was studied.The conclusion was accurate and its extremum function was given.After studying the single leaf radius of the double integral operator on the unit disk,the conclusion was gradual and accurate.

关 键 词：双积分算子 调和映照 极值函数 单叶半径
