| 摘 要： | 构造了一个描述气泡宏观运动的均匀非绝热模型，结合气泡的平衡机制，分析了空气和惰性气体的各种特性对单泡声致发光的平衡参数空间的影响．发现气体性质通过对平衡参数空间的影响对单泡声致发光起着重要作用．其中热传导系数起着主要作用，它的减小将导致气泡的平衡半径与压缩比增大，并导致发光亮度的增强．

| Abstract: | A uniform and nonadiabatic model which describes the macroscopic bubble dynamics was constructed and combined with bubble equilibrium mechanism for analyzing the effects of the characteristics of air and noble gases on equilibrium parameter space in single bubble sonoluminescence (SBSL). It is concluded that the characteristics of the gas inside a bubble have considerable influences on the equilibrium parameter space of SBSL. Among them, the thermal conductivity plays an essential role, smaller thermal conductivity will lead to larger ambient radius and ratio of bubble contraction, resulting in the increase of the light emission. |
