摘　　要：用矩量法计算了一种实际飞机的电磁散射。对于原始的输入数据 ,不可能得到正确的结果 ,尽管阻抗矩阵并不是病态的。把输入数据的节点和边重新安排且保持该飞机的外形尺寸于不动 。The electromagnetic scattering from a real aircraft is calculated by the method of moments (MoM).The correct solution can not be obtained for the original input data,even though the impedance matrix is not ill conditioned.By rearanging the order of the nodes and edges of the triangulation for the aircraft without changing its size and shape,a good solution has been obtained.

关 键 词：电磁散射 矩量法 病态 条件数 飞机 阻抗矩阵
