摘要: 在线性非平衡热力学中,昂萨格倒易关系对其发展起着极为重要的作用.昂萨格倒易关系大大减小了实验分析的困难和工作量,为从实验角度来确定唯象系数提供了可能.本文分别以温度T和体积V以及温度T和粒子数N为自变量证明了昂萨格倒易关系,并探索了熵产生率中力和流的物理本质.

关键词: 昂萨格倒易关系, 涨落, 唯象系数

Abstract: The Onsager s reciprocity relation takes the important role in the development of linearity nonequilibrium thermodynamics.The relation reduces difficulties and workload in experiment analysis so as to offer possibility to definite the phenomenological coefficient.This paper proofs the relation from independent variables:temperature,volume and temperature,number of particle,and investigates entropy production rate physics innate character,respectively.

Key words: Onsager s reciprocity relation, fluctuation, phenomenological coefficient
