摘要
从单个汽泡在过冷水中的振动方程出发，导出了汽泡破裂时噪声辐射的数学模型；从理论上分析了蒸汽在水下有限空间内喷注时喷注噪声的声源和辐射规律，并发现水的过冷度对噪声的声压级和频率影响非常显著，这一发现已被随后的实验所证实．
The mathematical model of a steam bubble, which breaks in subcooled water, is set up. Based on the model, the theoretical analysis on the origin of steam micro jet noise and the noise emission behaviors are carried out. It is found that the subcooling degree has a great effect on the noise level and frequency.
