摘      要：The compressibility of fluids has a profound influence on oscillating bubble dynamics,as characterized by the Mach ***,current theoretical frameworks for bubbles,whether at the first or second order of the Mach number,are primarily confined to scenarios characterized by weak ***,a critical need to elucidate the precise range of applicability for both first-and second-order bubble theories ***,we investigate the suitability and constraints of bubble theories with different orders through a comparative analysis involving experimental data and numerical *** focal point of our investigation encompasses theories such as the Rayleigh–Plesset,Keller,Herring,and second-order bubble ***,the impact of parameters inherent in the second-order equations is *** spherical oscillating bubble dynamics in a free field,our findings reveal that the first-and second-order bubble theories are applicable when Ma≤0.3 and 0.4,*** a single sonoluminescence bubble,we define an instantaneous Mach number,*** second-order theory shows abnormal sensibility when Mai is high,which is negligible when Mai≤*** results of this study can serve as a valuable reference for studying compressible bubble dynamics.
