摘要: |
统计物理是将大量粒子微观运动状态与系统的宏观性质联系起来,进而获得系统的热力学性质;配分函数则是联系系统微观量和宏观量的桥梁。基于统计物理相空间的概念,论述了配分函数的物理意义,给出不同系统配分函数在相空间中的表示,并结合实例介绍了其计算方法。 |

Abstract: |
Based on the meaning of the phase space,this paper discussed the quota function in statistical physics and given a method of expression and computation quota function of the various systems in the phase space.Finally,an example is presented. |
Key words: phase space,quota function,Boltzmann factor,ensemble |
