摘　　要：本文提出用保角变换边界元组合法计算各种结构的未屏蔽平板线特性阻抗问题．保角变换将未屏蔽平板线的无穷边界无界场城边值问题变换为有界场域边值问题，再利用具有诸多优点的边界元法进行求解．通过对各种结构的未屏蔽平板线的实例计算结果表明：组合法不仅具有较高的计算精度，而且可以很方便地应用于传输线工程问题的设计与计算．This paper describes the hybrid method to calculate characteristic impedance of various configuration of unscreened slab lines. Conformal transformation is used to trandform the infinite boundary into the finite boundary , and boundary element method is then applied to the computation of finite boundary boundary-value problems,The hybrid method has been applied to some real cases Excellent agreement with computed results obtained previously is demonstrated.
