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。
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。
The characteristic impedances of vertical,symmetrical, flat coupled strip lines are also given. 附帶地給出了直立式對稱平板耦合帶線特性阻抗的計算公式。
All paths through a system must be terminated with their characteristic impedance. 所有通過系統的通路都必須採用其特徵阻抗進行端接。
