摘要
分析了超声波纵波、横波、表面波3种波型的产生条件和声速关系,检测了超声波在固体表面的波型转换,并测量了声表面波的速度,讨论了声表面波在超声延迟线方面的应用.
The relationship of condition and sound velocity is analyzed for longitudine wave, transverse wave and surface wave. The transformations of ultrasonic waves on solid surfaces have been detected. The velocity of ultrasonic surface waves is measured. The application of surface wave in ultrasonic delay wires is introduced.
