| 摘 要： | 近独立粒子组成的孤立系统处于统计平衡态时,系统可能处于热力学平衡态,也可能偏离热力学平衡态,出现非热力学平衡态.不同的宏观状态(或分布)所包含的微观状态对宏观物理量的贡献是不同的.对系统不同分布的热力学概率进行了研究,获得了系统轻度偏离平衡态的概率分布规律,从而揭示出系统处于统计平衡态时宏观性质不随时间变化的物理本质.

| Abstract: | When it is in a statistic equilibrium state, the isolated system of approximate non-interaction particles may be in a thermodynamic equilibrium state, it may also be in deviation from thermodynamic equilibrium state. Thus, there appears a thermodynamic non-equilibrium state. The microscopic states contained in different macroscopic states offer different contributions to macroscopic physical quantities. The thermodynamic propability of different distributions in the system is studied. The propability distribution law of slight deviation from equilibrium state is obtained. Therefore, the physical nature is indicated that in statistic equilibrium state the macroscopic properties are not related to the time change. |
