This method is using two times conformal transformation method and mirror theory to calculate the characteristic impedance. 這種方法是採用兩次保角變換結合同軸線特性阻抗公式進行特性阻抗計算。
Through conformal mapping, the calculation method of its characteristic impedance the impedance is derived by converting the convoluted strip line into an asymmetric one. 通過保角變換將其特性阻抗的計算轉化為對非對稱型平板帶狀線特性阻抗的計算，並得出了卷繞型帶狀線特性阻抗的計算方法。
The paper describes the principle of wave impedance estimation using self-adap-tive filtering. 本文介紹了自適應濾波法波阻抗估計的基本原理。
The boundary between halite and areno-argillaceous rocks show distinct reflection features because there is a strong impedance difference between them. 鹽岩與砂泥岩體之間有較強的波阻抗差，因而其界面反射特徵明顯。
