不可逆性、分子混沌和第二定律的简单证明

Irreversibility, Molecular Chaos, and A Simple Proof of the Second Law

P. D. Gujrati

摘要:

统计系统的不可逆性可追溯到其概率演化,而分子混沌假设并不是通常所认为的唯一结果。在假设每个微观态几率的变化率只随时间的发散而为零的条件下,我们证明了一个系统在恒定能量下的熵不会随时间而减小。

英文摘要:

The irreversibility in a statistical system is traced to its probabilistic evolution, and the molecular chaos assumption is not its unique consequence as is commonly believed. Under the assumption that the rate of change of the each microstate probability vanishes only as time diverges, we prove that the entropy of a system at constant energy cannot decrease with time.
