摘要
本文首先说明用场量Ｂ，Ｈ或用向量磁住Ａ表述时，三维恒定磁场解答的唯一性；然后着重研究Ａ的向量泊蚣方程混合边值问题和Ａ的旋度旋度方程混合边值问题的唯一性，并进一步讨论了两者的等价性。
In this paper,the uniqueness of 3D magnetostatics for B and A formulation areproved at first, then the uniqueness of mixed boundary value problems of curl-curl equa-tio and vector Poisson equation are investigated in detail; finally,the equivalence be-tween these two equations are discussed.
