| 摘 要： | 文章给出声波在气－液混合物中的传播方程。根据声压的频谱导出相应的共振态气泡的份额。引入临界气泡份额和极大声压相应的气泡份额，推断出共振态气泡份额与相应声压之间存在线性关系。

| Abstract: | The propagation equation of sound wave in gas liquid mixtures is given.According to the spectra of sound pressure the predictions of the resonant bubble fraction are deduced.The critical bub fraction and the bubble fraction which corresponded with the maximum sound pressure are introduced,it concluded that the non linear relation between the resonant bubble fraction and the corresponding sot pressure is present. |
