事务对象是值封送的对象，这意味着跨应用程序域边界（即使在同一进程中）传递它的任何尝试都将导致事务对象的序列化。
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。
