| 摘 要： | 在Ｌｏｍｍｅｌ的振动压力场近似公式中引入了多相及多成分混合物中的声波传播速度公式，计算了容器内振动体在多成分混合物中产生的压力场。计算结果表明，在振动试件表面附近可产生很高的压力，振动压力场沿空间位置发生脉动变化。振动装置产生的压力波沿振动方向传播很快，而沿横向传播较慢。

| Abstract: | By introducing the sonic speed formula of a multi component mixture into Lommel's
formula, the acoustic pressure in a mixture is calculated. The results show that the pressure near
the surface of vibrating tip is very high, and the pressure pulses in mixture. The pressure wave
resulted from vibratory facility propagates along the direction of vibration quickly, and along
lateral direction slowly. |
