【摘要】 对折射波束在液－液界面上的现象进行了数值和实验研究。结果表明:当声束从声阻抗大的介质入射到液－液界面上时,折射声束会存在反向位移现象。更多还原

【Abstract】 The phenomenon of refracted beam shift on a liquid-liquid interface is studiedby using numerical and experimental methods. Result shows that when acoustical beamis incident from a medium with larger acoustical impedance, there exists a shift of therefracted beam.更多还原
