各态历经假说各态历经假说ergodichypothesis企图把统计规律还原为力学规律的一种假设。1871年由L.玻耳兹曼提出。他认为，一个孤立系统从任一初态出发，经过足够长的时间后将经历一切可能的微观状态。20世纪初，P.厄任费斯脱夫妇又提出了准各态历经假说，把上述假说中的“历经”修改为“可以无限接近”。各态历经假说或准各态历经假说的基本思想是，认为系统处于平衡态的宏观性质是微观量在足够长时间的平均值，企图用力学理论证明统计物理学的基本假设。当研究对象从少量个体(如分子、原子)变为由大量个体组成的群体时，后者所遵循的统计规律与前者所遵循的力学规律本质上是不同的，统计规律不是力学规律的结果，不能由力学规律推导出来。因此，试图把统计规律还原为力学规律的各态历经或准各态假说是不正确的，满足假说的系统并不存在，这类假说不能代替统计规律作为统计物理学的基础。
