摘　　要：本文从格林积分公式及格林函数出发推导出以ｒＡ及为求解量的轴对称静磁场的矢量边界元法。与以往的以Ａ及为求解量的矢量边界元法相比，本文所推导的方法具有易于处理边界端点与交界面条件，并易于同有限元法结合的特点。通过对两个静磁场问题的计算分析，表明所建立的方法是可行的，具有较高的精度，可以很方便地应用于具有轴对称特性的电工设备的静磁场分析与设计。The vector potential boundary element method for the axisymmetric magnetostatic field are derived from the integral identity and the three dimensional Green's function,whose unknowns are rA and.Compered with the general boundary element method, which takes A and on as the unknowns, the method presented in this paper can easily copy with the end point of the boundary and the interface condition, and also easily combined with the finite element method. By calculating and analysing two examples, it is proven that the new method is reliable, and has high accuracy, and can be used in analysing the magnetostatic field of axisymmetric equipment in electrical engineering.
