利用单位球上的Green形式将单位球上的问题转化到了单位球面上，利用单位球上的H^2 Hardy空间定义出一个算子．在证明这样的算子有界的情况下，利用Hahn-Banach定理及Reize表示找到了δ^-方程的解，并且给出了此解的范数估计．

英文摘要：

With the Green function of unit ball, the problem of unit ball is turned to that of spherical surface, and an operator is defined by H^2 Hardy space in the unit ball. After this operator is proved to be bounded, Hahn-Banach Theorem and Reize representation are employed to solve the δ^- equation. Furthermore, this paper presents the estimate of the solution.
