由于阻抗法易受过渡电阻、互感器误差、线路结构不对称等因素的影响，所以测距精度不高。
Because the impedance fault location method is easily influenced by the factor such as fault resistance, transformer error and asymmetrical line configuration, the fault location accuracy is lower.
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。
The traditional fault location method based on impedance can not overcome the effects of transition resistance, etc.
现代应用较多的吸声层大部分是阻抗过渡式结构，但是厚度有限，无法满足低频吸声的要求。
Now most sound absorption layers are impedance transition constructs, which have been used widely, but their thickness is limit and cannot meet the need of absorbing sound at low frequency.
