| 摘 要： | 本文从理论上与实验上研究了纯高岭土悬浮液中的声传播问题。在理论上考虑了悬浮粒子在声场中的电力相互作用与流体动力相互作用,对Ahuja的理论作了些改进;在实验上我们测量了在室温条件下声速和声振幅吸收系数对频率的依赖关系。理论与实验的一致性是相当好的。

| Abstract: | The propagation of sound wave in kaolint suspensions from theoretically and experimentally. Ahuja's theory is modified for the effects of eletric interaction and hydrody-namic interaction of suspended particles in sound field. Under the condition of chamber temperature, one measured velocity of sound and absorption coefficient versus frequeney. It's shown that theoretical results are in good agreement with the experiment data. |
