摘　　要：本文提出了一种解决开域轴对称静磁场问题的混合有限元边界元法。基于矢量边界元法公式，混合有限元边界法以适合轴对称静磁场问题的ｒＡ与νｒｒＡｎ作为基本求解量，并进一步改进成仅以ｒＡ作为求解量，这样便降低了混合方程组求解量的数目，节省了所占用的计算机存贮容量。文中给出了三个应用实例。In this paper, a formulation of hybrid finite element boundary element method for solving the axisymmetric magnetostatic field problems with open boundaries is presented, the variables rA and νr ο rA ο n , which fit the axisymmetric problems better, are chosen as the unknowns. To further simplify the solving procedure, only the variable rA is accepted as the unknown. Three applications are given as tests of the presented method.
