| 中文摘要: |
| 为了在应力测量中更好地测量超声波的纵波声速和横波声速，提高测量的精度和准确性，本文研究了一种由两种不同频率的纵波晶片（f11＝2MHz，f12＝5MHz）和两片偏振方向相互垂直的横波晶片（ft=5MHz）组成的复合型超声波探头，研究了它的几种组合的发射与接收MASON等效电路图，并报道了它的一些实验结果． |
| 英文摘要: |
| In order to achieve better measurements of ultrasonic velocities of longitude wave and shear wave, as to raise the measurement precision and location acuracy a compound ultrasonic transducer, which consists of two longitudinal wave wafers of different frequencies (f11 =2MHz,f12=5MHz) and two shear wave wafers of the same fre-quency(ft=5MHz), was designed. Its MASON equivalent circuits of emission and receip-tion for different combination were investigated. Some experimental results are presented. |
