Piezoelectric actuator controlled by electric field shows serious hysteresis and creep phenomena, which severely degrades the positioning accuracy.
压电陶瓷致动器在电场驱动下会产生迟滞和蠕变现象，降低了定位精度。

The hysteresis in piezoelectric actuator is the main factor that affects its displacement accuracy.
压电驱动器的迟滞特性是影响其位移输出精度的主要因素。
3
Near the transition temperature, a thermal hysteresis was found in dielectric, pyroelectric and piezoelectric measurements. Thus the transition should be of the first order transition.
