According to this , the research of the fatigue properties of the ferroelectric films was proposed . the lead zirconate titanate ( pzt ) film was prepared by a metal - organic decomposition method . the films " physical properties were analysed by x - ray diffraction ( xrd ) , scanning electron microscopy ( sem ) and hysteresis loops 然后采用金属有机物热分解法制备出作为研究对象的锆钛酸铅pb ( zr ， ti ) o _ 3 ( pzt )薄膜，用x射线衍射仪、扫描电镜和rt6000s铁电测试仪测量表征铁电薄膜。
In recent several decades , ultrasonic phased arrays had been applied to many medical specialties and nondestructive evaluation ( nde ) . an ultrasonic phased array consists of multiple elements which are usually cut or etched from a single piezoelectric plate of lead zirconate titinate ( pzt ) . the element thickness determines the operating frequency of the transducer 近年来，随着科学技术的飞速发展，超声相控阵已广泛的应用在医学、无损检测等方面，所谓相控阵，就是由多个压电陶瓷片(阵元)按一定的分布排列，然后逐次按欲先规定的延迟时间激发，就可以实现声波的聚焦。
The lead zirconate titanate ( pzt ) / polymer composite presented large tan5 and dynamic modulus when the composites were exposed to higher polarization voltage and longer polarization time , because of the uniform dispersion of ceramic in polymer matrix and the strong interaction between grain and polymer . the morphology of the composites , namely the degree of the grains dispersion in polymer , can be observed through scanning electric microscope ( sem ) 颗粒结构性高的压电陶瓷，其复合体系内耗大；在高极化电压、长极化时间下，压电陶瓷颗粒在聚合物中分散比较均匀，与聚合物接触面大，相互间作用强；在外力作用时，体系tanb 、 g ， ， g ?呈现大的值。
