对水平振动平板上由几千个钢球组成的钢球团的动力学进行了实验研究。当填充率（颗粒数量）增加时，会发生从随机排列且几乎独立移动的颗粒到二维晶体状结构的过渡。这种转变的定量特征在于从球的对分布函数获得的序参数。
The dynamics of a cluster consisting of a few thousand steel spheres on a horizontally vibrated plate is studied experimentally. A transition from randomly arranged and almost independently moving particles to a two-dimensional crystallike structure occurs when the filling fraction (the number of particles) is increased. This transition is quantitatively characterized by an order parameter obtained from the pair distribution function of the spheres.
