| Abstract: | 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. |
