波在颗粒物媒质中的传播特性

Properties of Wave Propagation in a Granular Medium

颗粒状物质是介于固态和液态之间的一种特殊的物态形式，有其独特的物理性质．我们通过计算机模拟实验，研究波在颗粒物媒质中的传播速度与压强的关系、颗粒物间摩擦系数对传播速度的影响．

Granular material, as an unusual state of matter between solid and liquid, has its ownphysical properties. In this paper we study, by computer simulating, the relationship betweenthe pressure and the velocity of wave propagation in a granular medium, as well as the effect ofthe frictions between particles on the propagation velocity.
