Examples
- The auther also predicted the function of interference effect after analyzing the experimental curves , deducted the theoretical emission noise of two bubbles and mass bubbles under the interference effect . in order to predict precisely the emitted noise from mass traveling bubbles , the paper also studied the distribution of air nucle i in water
作者还通过对实验所得的曲线的分析预计到干涉效应的作用，并推导了有干涉效应存在的条件下两个空泡以及空泡群的理论辐射噪声，另外，为了对群泡辐射噪声进行更精确的估算，还研究了水中气核的分布。 - 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。
