摘要
从系综理论出发,导出了由任意数目和不同质量的刚性粒子构成的二维和三维力学系统的正则分布函数及能量涨落公式,我们的计算机模拟与该理论一致.
Starting from the Gibbs ensemble theory, we derive the canonical distribution function and energy fluctuation formula for two-dimensional and three-dimensional mechanic systems that consist of arbitrary number and different masses of rigid particles. The results of our computer simulation are in agreement with the theory.
