摘　　要：本文以系综理论为根据,导出了任意数目、质量不同的刚性粒子构成的二维及三维近独立子系系统的分布函数,并与计算机模拟实验的结果进行了比较.In this paper, according to Gibbs micro-canonical ensemble theory, we have derived the distribution function of the two and three-dimensional quasi-independent particle system, which is composed of a random number of rigid particles with different mass. And we have compared these functions with the results of computer simulations.

关 键 词：系综理论 分布函数 计算机模拟
