中文摘要：

以水为工作介质,考虑了液体的可压缩性,研究了声场中气泡的运动特性,模拟了声波频率、声压幅值、气泡初始半径以及液体的表面张力和黏滞系数的变化对气泡运动状态的影响.分析了空化处理效果与气泡运动状态之间关系.结果表明：气泡运动处于混沌状态,是提高声空化降解有机污染物能力的最重要因素.

英文摘要：

Considering liquid compressibility,the dynamical behaviors of gas bubble in acoustic field are investigated by regarding water as a work medium.The effects of acoustic frequency,acoustic pressure,initial radius of gas bubble,liquid surface tension,and viscosity coefficient on bubble motion state are numerically simulated.The relationship between cavitation treatment effect and gas bubble motion state is analysed.The results show that when the gas bubble motion is in a chaotic state,it is the most important factor for enhancing acoustic cavitation degradation of organic pollutants ability.
