| 摘 要： | 以气泡壁处声压和径向振动速度为边界条件，研究气泡对声传播的影响；给出了含气泡介质内声速的表达式，得到了声速随气泡体积分数及声波频率的变化图。表明：声波频率一定时，声速随着气泡体积分数增大而减小；气泡体积分数一定时，频率增大对声速的影响较小。

| Abstract: | By boundary conditions of pressure and radial vibration velocity in bubble wall, the effect of bubble on propagation of acoustic wave is researched; the formula of sound speed is presented, and the curves of sound speed following the changes of bubble volume fraction or frequency are charted. The conclusions are shown： given the same frequency, the sound speed decreases with increasing of the bubble volume fraction; given the same bubble volume fraction, there is almost no influence induced by frequency to sound speed. |

| Keywords: | sound speed bubble volume fraction frequency |
