比较分析了PIPWP法和PEA法测量固体电解质中空间电荷分布的原理。在时域和频域中分别给出了PIPWP法的电流信号和PEA法的电压信号与试样中电荷分布的关系。此外，还介绍了利用数学解卷积技术对两种方法的累积电荷密度进行标定的方法。为了比较这两种方法，在电子辐照的PMMA样品中的电荷分布进行了观察。两种方法的结果显示电荷累积测试样品的电荷轮廓信号完全相同，位置分辨率为20μm。此外，还讨论了由测量的电荷分布得到的样品中的电场分布和电势分布。
The principles of both PIPWP and PEA methods for measuring the space charge distributions in solid dielectrics are comparatively analyzed. The relationship between the charge distribution in a specimen and the current signal of PIPWP method or the voltage signal of PEA method are expressed in the time domain and frequency domain. Furthermore, the calibration method of amount of accumulated charge density, using mathematical deconvolution technique, was described for both methods. To compare the two methods, the charge profiles in the electron irradiated PMMA samples were observed. The results of both methods show the exactly same charge profile signal for charge accumulated test sample with the position resolution of 20μm. Furthermore it is discussed on the electric field distribution and electric potential distribution in the sample which were obtained from the measured charge profiles.
