The impedancetransition of the films was studied under different applied voltages.
研究了在不同的电压作用下薄膜的阻抗转变规律。

The traditional fault location method based on impedance can not overcome the effects of transition resistance, etc.
传统的阻抗法进行故障定位，难以克服过渡电阻等因素的影响。

Now most sound absorption layers are impedancetransition constructs, which have been used widely, but their thickness is limit and cannot meet the need of absorbing sound at low frequency.
