同时引入了小波方法对瞬态的空化噪声信号进行了分析，取得了良好的效果。 - Firstly it discusses the value , meaning , background and method of this topic . then it deducts the single - bubble sound pressure , spectrum of sound pressure , power spectrum . according to the real situation of traveling bubble cavitation noise around a schiebe body , the mathematical model of single - bubble collapse is selected , furthermore , the mathematical model of mass traveling bubbles without interference effect is established , and the multi - peaks and rebound phenomenon while bubbles collapse is also analyzed with statistical method
首先论证了本项研究的意义，价值，背景和方法，然后推出了单空泡辐射噪声声压，声压谱和功率谱，针对回转体流动泡空化噪声的具体情况，选择了双指数模型作为单空泡溃灭的数学模型，进一步建立了无干涉条件下的群泡辐射噪声的数学模型，并用统计的方法分析了空泡溃灭时的多峰值和反弹现象。 - The extend work of my doctoral research is introduced in the part . problems of cavitation noise are investigated with three methods such as theory analysis , numerical simulation and experiment research . mixed boundary element method is put forward to solve acoustics of bubble collapse by author
第二部分：空化噪声研究该部分工作是作者博士期间工作的延续，对空化噪声问题从理论分析方面、数值模拟及实验三方面进行研究，应用作者提出的混合边界元方法求解了空泡在边界附近溃灭时的辐射噪声问题。
