摘要:

证明了封闭系统的子系统的正则分布直接来自于总能量严格守恒的时间可逆牛顿运动方程的解。结果表明,这一结论适用于可积或不可积系统,即使整个系统可能包含少至几千个粒子。换句话说,我们证明了正则分布适用于实验相关的大小和观测时间的子系统。

英文摘要:

It is demonstrated that the canonical distribution for a subsystem of a closed system follows directly from the solution of the time-reversible Newtonian equation of motion in which the total energy is strictly conserved. It is shown that this conclusion holds for both integrable or nonintegrable systems even though the whole system may contain as little as a few thousand particles. In other words, we demonstrate that the canonical distribution holds for subsystems of experimentally relevant sizes and observation times.
