| Abstract: | 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. |
