利用脉冲电声方法研究了直流应力作用下玻璃材料中空间电荷的积累特性。然而，观测到的信号是一个无法理解的信号。为了理解观察到的信号，用PET薄膜作为电荷注入的抑制层，对玻璃材料进行了测量。通过测量发现，在直流应力作用下，玻璃材料中积累了超空间电荷。无法理解信号的原因之一被认为是声阻抗不匹配。因此，本文通过计算样品与电极界面处的信号比，对观测到的声信号进行分析。
The characteristics of space charge accumulation under DC stress in glass materials were investigated using the pulsed electro-acoustic method. However, the observed signal was an incomprehensible signal. To understand the observed signal, a measurement of the glass material with a PET film, which was used as a suppression layer for charge injection, was carried out. From this measurement, it is found that hetro space charges were accumulated in glass material under DC stress. One of the reasons for the incomprehensible signal is thought to be a mismatch of acoustic impedance. Therefore, in this paper, the analysis of observed acoustic signal was carried out by calculating the signal ratio at the interface between the sample and electrodes.
