specfic impedance的用法和樣例：
例句
- 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。
