摘要

摘要: 研究了冲击波倾斜入射PZT95/5铁电陶瓷时的放电特性。结果表明，在小负载条件下，随着入射倾斜角的增加，PZT95/5铁电陶瓷放电电流波形前沿变缓，脉宽时间增加，波形从单脉冲方波演变成梯形波，甚至锐变成三角波。

Abstract: The current waveform of Ferroelectric ceramics PZT95/5 depoling under tilted shock wave compression has been studied. Analytic model was established to analyze the effects of incident angle on the rising time, duration and peak amplitude of the depoling current. Experiments were conducted as well to confirm these effects. Results indicted that with the increasing of incident angle, the depoling current rises with longer time, pulse duration becomes broad and the peak amplitude keeps constant until the waveform decays into triangular form.
