从微观力学出发，推导了导热非平衡定态的热力学关系式。扩展的克劳修斯关系使人们能够在实验上确定热流中二阶的非平衡熵。与之相关的类似香农的熵微观表达是有启发意义的。当热流一定时，扩展的Gibbs关系提供了线性非平衡区中热力学作用力的统一处理。
Starting from microscopic mechanics, we derive thermodynamic relations for heat conducting nonequilibrium steady states. The extended Clausius relation enables one to experimentally determine nonequilibrium entropy to the second order in the heat current. The associated Shannon-like microscopic expression of the entropy is suggestive. When the heat current is fixed, the extended Gibbs relation provides a unified treatment of thermodynamic forces in the linear nonequilibrium regime.
