摘　　要：通过PZT水听器对不同粘度粘性液体中激光空泡脉动辐射的声波特性进行了实验,获得了粘性液体中激光泡声波并进行分析.分析结果表明:激光空泡在脉动过程中辐射的声波将受液体粘性影响,粘性系数越大,辐射声波强度越弱,峰值频率呈现增大的趋势.The properties of laser-induced cavitation bubble collapse sound waves during the high-power laser and matter interaction in different viscous liquids were investigated by the piezoelectric transducer（PZT） hydrophone.The experimental results indicate that the liquid viscosity has an obvious influence on laser-induced cavitation bubble collapse sound waves,larger viscosity makes the intensity of sound waves more feeble,and the peak of frequency becomes higher and higher.
