中文摘要：
这块地水平地极化了超声砍 2/2 散发的波浪压电的合成正常探查被学习。严格地，二不同表面力量的分析领域解决方案被推出，领域分发和择向性模式被数字计算给。垂直的散发的地砍波浪理论上并且与实验相比被获得。择向性模式的试验性的结果遵守了理论预言，它为变换器的设计申请提供了理论基础。
英文摘要：
The field of horizontally polarized ultrasonic shear wave radiated by a 2/2 piezoelectric composite normal probe was studied. The strictly analytic field solutions for two different surface forces were deduced and the field distribution and directivity patterns were given by numerical calculations. The vertical radiated field of shear wave was obtained theoretically and compared with experiment. The experimental result of directivity pattern conformed the theoretical prediction, which provided the theoretical basis for the engineering application of the transducer.
