Using experimentally determined values as parameters and a modified Rayleigh-Plesset equation,we compute the cavitation kinetics of medical microbubble of different size driven by nonlinear wave in viscous fluid.The results show that the occurrence probability of cavitation（OPC） will increase with sound pressure and drifts in the direction of radius reduced under an exciting frequency.The OPC is also correlated significantly with material parameters of microbubble.The more the cycle number of ultrasonic is,the larger the OPC has become,and th...
