impedance matrix的用法和样例：
例句
- Numerical results suggest that the SDT avoids internal resonance efficiently and finishes impedance matrix inversion fast and accurately.
数值方法表明，同传统矩量法相比，空间分解技术的使用，有效避免了内谐振的产生，加速了阻抗矩阵的求逆。 - The correct solution can not be obtained for the original input data,even though the impedance matrix is not ill-conditioned.
对于原始的输入数据，不可能得到正确的结果，尽管阻抗矩阵并不是病态的。
