摘　　要：根据理想导体的边界条件建立线、面连接结构的电场积分方程。该积分方程运用矩量法直接进行计算时,随着电尺寸增大,计算量和存储量就会迅速增加,进而降低了求解的效率。为了降低计算量和存储量,运用H2矩阵方法的可容许条件将阻抗矩阵元素划分为远区场的矩阵块和近区场的矩阵块。近区场的矩阵块直接用矩量法计算并进行存储,远区场的矩阵块通过H2矩阵的层间插值的方法进行处理并存储,从而有效地降低了计算量和存储量。In this paper, based on perfect conductor boundary conditions building the electric field integral equation of wire attached to an arbitrary faceted surface. When using the method of moments to calculate directly, with the increasing size of electrical conductor, computation and storage will increase rapidly, thereby reducing the efficiency of solution. In order to reduce the computation and storage, using the permissible conditions of the H^2-Matrix to divide the elements of impedance matrix into far field and near field. Matrix block of near field can be calculated and stored directly by using the method of moments, while matrix block of far field can be disposed and stored by method of interpolation between layers of H^2-Matrix, thus greatly reducing the amount of computation and storage.
