| 摘 要： | 在气炮加载条件下，分别测试了两种晶粒度的PZT95／5铁电陶瓷样品在冲击波作用下的击穿电压，并采用Weibull分布分析了所获得数据．结果表明，PZT95／5铁电陶瓷在冲击波作用下的击穿电压分布可以用二参数Weibull分布模型描述，从击穿电压密度分布函数和失效率函数来看，晶粒度为2．5μm的PZT95／5样品的击穿电压分布优于晶粒度为7μm的PZT95／5样品击穿电压分布．

| Abstract: | Breakdown voltages of two kinds of PZT95/5 ferroelectric ceramics with different grain sizes were investigated under shock compression. Weibull distribution model was used to analyze the experimental data. The results show that the breakdown voltage of PZT95/5 samples can be described by two parameter Weibull distribution. According to the density function and failure probability function of the Weibull distribution, PZT95/5 ceramics with fine grains possess more optimum breakdown voltage distribution than PZT95/5 ceramics with coarse grains. |
