本文综述了一类非平衡介观过程局部详细平衡条件的物理意义和数学实现。一个中心概念是波动熵通量，其稳定平均值给出平均熵产生率。我们重复一下，局部详细平衡本质上等同于广泛讨论的熵通量的波动关系，因此最多“只是故事的一半”。''
We review the physical meaning and mathematical implementation of the condition of local detailed balance for a class of nonequilibrium mesoscopic processes. A central concept is that of fluctuating entropy flux for which the steady average gives the mean entropy production rate. We repeat how local detailed balance is essentially equivalent to the widely discussed fluctuation relations for that entropy flux and hence is at most ``only half of the story.''
