提出了一种测量电介质中空间电荷现象的脉冲电声法。该方法不仅适用于高分子材料中的空间电荷测量，也适用于其它材料中的空间电荷测量。最近，PEA方法也被应用于多层电介质。在这种情况下，认为测量误差是由测量噪声的声学特性的差异造成的。从理论上介绍了PEA测量中应注意的问题。本文利用数值分析的方法讨论了两层介质中PEA法的传感器信号对声阻抗差异的影响。
The pulsed electroacoustic (PEA) method has been developed to measure space charge phenomena in dielectric. This method is widely used for the space charge measurement in not only polymer and but also other materials. Recently, the PEA method has also been applied to the multi-layer dielectric. In the case, it is considered that the measurement error is made by the difference in the acoustic characteristics of measuring dielectrics. And some attentions on PEA measurement was reported, theoretically. We have discussed the sensor signal on PEA method in two-layer dielectric by using numerical analysis to discuss the influences on the difference in the acoustic impedance in this report.
