介绍了一种新的压电材料，特别是锆钛酸铅（PZT）陶瓷在交变电场作用下电容变化的动态测量方法。该方法可以将由于非线性效应引起的电容变化与由于温度变化引起的电容变化分开，以获得绝热非线性系数，固定非线性系数的符号，并确定系数的每个阶次，从而将电容变化的阶次作为所施加电场的函数分开。
The development and application of a new dynamic measuring method of capacitance variation of piezoelectric materials, especially of lead zirconate titanate (PZT) ceramics, with an alternating electric field are presented. This method makes it possible to separate the capacitance variation due to nonlinear effect from that due to temperature change, to obtain the adiabatic nonlinear coefficients, to fix the sign of the nonlinear coefficient, and to determine each order of coefficients, separating the orders of the capacitance variation as a function of the applied electric field.
