The paper describes the principle of wave impedance estimation using self-adap-tive filtering. 本文介绍了自适应滤波法波阻抗估计的基本原理。
The boundary between halite and areno-argillaceous rocks show distinct reflection features because there is a strong impedance difference between them. 盐岩与砂泥岩体之间有较强的波阻抗差，因而其界面反射特征明显。
This method is using two times conformal transformation method and mirror theory to calculate the characteristic impedance. 这种方法是采用两次保角变换结合同轴线特性阻抗公式进行特性阻抗计算。
Through conformal mapping, the calculation method of its characteristic impedance the impedance is derived by converting the convoluted strip line into an asymmetric one. 通过保角变换将其特性阻抗的计算转化为对非对称型平板带状线特性阻抗的计算，并得出了卷绕型带状线特性阻抗的计算方法。
