摘　　要：通过考虑Van der waals方程中不同气体的绝热指数和热扩散系数,计算了惰性气体参数对声致发光的影响.利用R-P方程,分别计算了He,Ar和Xe气泡在声致发光过程中的相对半径和最高温度.利用韧致辐射模型计算了相应惰性气体声致发光的光强.计算结果表明随着惰性气体分子量的增加,气泡内的最高温度和最大光强也随之增加.The influence of noble gas bubbles on single bubble sonoluminescence was analyzed by considering the effect of the van der Waals equation in the gas＇ s effective polytropic exponent and thermal diffusion coefficient. Using the R-P equation, the relative radius and maximum temperature of He, Ar and Xe bubbles on single bubble sonoluminescences were calculated. The light intensity of the corresponding noble gas was calculated by the bremsstrahlung model. The maximum temperature and light intensity of the bubble increased with the increase of the molecular weight of the noble gas.
