A layer of granular material on a vertically vibrating sawtooth-shaped base exhibits horizontal flow whose speed and direction depend on the parameters specifying the system in a complex manner. Discrete-particle simulations reveal that the induced flow rate varies with height within the granular layer and oppositely directed flows can occur at different levels. The behavior of the overall flow is readily understood once this feature is taken into account.
在垂直振动的锯齿形基座上的一层颗粒材料呈现出水平流动，其速度和方向以复杂的方式取决于指定该系统的参数。离散粒子模拟表明，诱导流速在颗粒层内随高度变化，并且在不同高度可能出现方向相反的流动。一旦考虑到这一特征，整体流动的行为就很容易理解了。
