中文摘要：

在里面之间并且在一个成穴水泡外面集体交换有几种交换形式的一个复杂过程一起正在行动例如煤气的散开，煤气液体的阶段转变，化学反应等等。一个现象学的模型集体交换被建议，在哪个压力差别被看作开车。与以前的物理模型相比，它有一种更简单的形式和不太计算的费用。把它与 Rayleigh-Plesset 方程相结合，当时，平衡半径被计算集体交换完成动态平衡。结果证明平衡半径有多重价值。在平衡半径和开车超声(压力振幅和频率) 之间的关系被评估。我们也调查了这些关系怎么被模型参数影响。最后，在不同压力驾驶的硫磺的酸的水泡半径进化被测量。平衡半径与压力改变的试验性的结果同意数字结果很好。

英文摘要：

The mass-exchange between the inside and outside of a cavitation bubble is a complicated process with several kinds of exchange forms acting together, such as gas diffusion, gas-liquid phase transition, chemical reactions and so on. A phenomenological model of mass-exchange was proposed, in which the pressure difference is considered as the drive. Compared with the previous physical models, it has a simpler form and less computational cost. Combining it with Rayleigh-Plesset equation, the equilib- rium radius is calculated when the mass-exchange achieves the dynamic balance. The result shows that the equilibrium radius has multiple values. The relationships between the equilibrium radius and the driving ultrasound （pressure amplitude and frequency） are evaluated. We also investigated how these relationships were affected by the model parameters. Finally, the bubble radius evolution in the sulfuric acid driven by different pressures was measured. The experimental result that the equilibrium radius changes with the pressure agrees with the numerical results well.
