摘要

本文测量了聚氯乙烯的热激电流(TSC)光谱和自发电流。在不同的极化温度下,热释电产生的电流的大小和方向是不同的。实验中在该温度以上出现了一个转变极化温度,电流为正,且随着极化温度的降低而减小;低于这个温度,电流是负的;在这个温度附近,电流很小。

Pyroelectrical phenomena in PVC
The Thermally Stimulated Current (TSC) spectra of PVC and spontaneous currents were measured in this paper. The magnitude and the direction of the currents caused by pyroelectricity vary at different polarizing temperature. A transition polarizing temperature appears in the experiment above the temperature, the currents are positive and decrease with the decrease of polarizing temperature; below the temperature, the currents are negative; near the temperature, the currents are very little.
