A non-equilibrium isolated macroscopic system spontaneously changes into an equilibrium one. The origin of such a well-known thermodynamic phenomenon has been left unclear since the 19th century. This paper shows that irreversible thermodynamic laws can be directly deduced from quantum mechanics if we investigate an isolated system from a new standpoint of looking at it from the inside. This result implies the achievement of a long-awaited target of directly constructing thermodynamic laws from quantum mechanics and leads to the completion of thermodynamics. The result also opens up a new view that diverse macroscopic irreversible phenomena including self-organization and evolution in living organisms can be regarded as macroscopic quantum phenomena and discloses a possibility of producing artificial life and intelligence with a non-mechanical character, for example, those with free will and creativity, through thorough pursuit of an ingenious combination of irreversible processes based on quantum mechanics.

从量子力学直接构造热力学定律

一个非平衡孤立的宏观系统自发地变成一个平衡系统。自19世纪以来，这种众所周知的热力学现象的起源就一直不清楚。本文表明，如果我们从新的角度从内部研究隔离系统，则可以直接从量子力学中推导出不可逆的热力学定律。这一结果意味着实现了期待已久的直接从量子力学构建热力学定律的目标，并导致了热力学的完成。
