研究了富锆锆钛酸铅（PZT）块体陶瓷动态迟滞的温度标度关系。在每一条关系曲线上，都有一个不连续区，对应着低温相变和高温相变。温度分为低T区和高T区。在每个温度区域，三个幂律标度关系得到的滞后面积ε A ε，矫顽力Ec，和剩余极化Pr与T，分别。六种温度标度关系都是场相关的，简化形式与从软、硬PZT陶瓷得到的结果不同。
The temperature scaling relations of the dynamic hysteresis were investigated in Zr-rich lead zirconate titanate (PZT) bulk ceramics. At each relation curve, there is a discontinuous district corresponding to the low- and high-temperature phase transitions. The temperatures are divided into low-T region and high-T region. At each temperature region, three power-law scaling relations were obtained for hysteresis area ⟨A⟩, coercivity Ec, and remnant polarization Pr with T, respectively. The six temperature scaling relations are field dependent and the simplified forms are different from the results obtained from the soft and hard PZT ceramics.
