为了研究单层水平振动颗粒系统中的颗粒分离现象,将一种基于平均场理论的统计力学方法运用到格点化的单层水平振动颗粒体系中.考虑由2种不同大小颗粒组成的体系,给出了体系的哈密顿量和配分函数.计算出了颗粒的分布趋势,计算结果在一定程度上解释了单层水平振动颗粒体系中不同大小颗粒的分离现象.
The granular separation phenomenon in the monolayer horizontal vibration granular system was studied with the mean field statistical mechanics method. Granular systems of 2 kinds of size granular compositions were considered. The granular distributed tendency was calculated, which can explain the granular segregation phernomenon in the monolayer horizontal vibration granular system.
