纵波直探头垂直入射固体界面产生横波试验
Test of the Transverse Wave Produced by Vertical Incidence of a Longitudinal Transducer which Entered on the Solid Interface Vertically
摘 要
分析了固体介质中,纵波传播过程中心轴线介质质点的纵向振动及周围质点的斜向振动状态,定量计算了纵波直探头垂直入射固体界面后横波出现的位置并进行了试验.结果表明,纵波直探头垂直入射固体界面时,在第二介质中也会产生横波,其强度远小于纵波.

Abstract
In this paper,both the longitudinal direction vibration state of medium particle in the central axis and the oblique direction vibration state of medium particle around the central axis were analyzed during the longitudinal wave propagation process of solid dielectric.The position of the transverse wave that followed the longitudinal wave was quantitatively calculated and experimentally verified.The results proved that the intensity of transverse waves produced in second medium was much less than the the intensity of longitudinal waves,when the longitudinal transducer entered on the solid interface vertically.
