Abstract

The dynamics of free and forced vibrations of a chain of particles are investigated in a harmonic model taking into account the retardation of interactions between atoms. It is found that the retardation of interactions between particles leads to the non-existence of stationary free vibrations of the crystal lattice. It is shown that in the case of a stable lattice, forced vibrations, regardless of the initial conditions, pass into a stationary regime. A non-statistical dynamic mechanism of the irreversible thermodynamic equilibration is proposed.

晶体不可逆热力学平衡的微观动力学机制
在考虑原子间相互作用延迟的调和模型中,研究了粒子链的自由振动和强迫振动动力学。发现粒子间相互作用的延迟导致晶格不存在固定的自由振动。结果表明,在稳定晶格的情况下,无论初始条件如何,强迫振动都会进入静止状态。提出了不可逆热力学平衡的非统计动力学机理。
