颗粒气体的实验实现和研究通常需要对粒子系综进行初始或永久的机械或电磁激励。一种典型的方法是通过振动板或容器壁提供能量。我们研究了这种激励圆柱形粒子的正弦振荡壁的效率，并表征其自由度的激发粒子的动能分布。分析了激励频率和激励幅值的影响。
The experimental realization and investigation of granular gases usually require an initial or permanent excitation of ensembles of particles, either mechanically or electromagnetically. One typical method is the energy supply by a vibrating plate or container wall. We study the efficiency of such an excitation of cylindrical particles by a sinusoidally oscillating wall and characterize the distribution of kinetic energies of excited particles over their degrees of freedom. The influences of excitation frequency and amplitude are analyzed.
