我们研究非平衡过程的时空热力学。我们首先利用视界外的观察者来推广时空热力学的公式。然后构造了f(R)重力下非平衡过程的时空热力学熵平衡方程。膨胀项和剪切项的系数等于黑洞膜模型的黏度，出现了一个新的熵产项。
We study space–time thermodynamics for nonequilibrium processes. We first generalize the formulation of space–time thermodynamics by using an observer outside the horizon. Then we construct the entropy balance equation of space–time thermodynamics for nonequilibrium processes in f(R) gravity. The coefficients of the expansion and shear terms are equal to the viscosities of the black hole membrane paradigm, and a new entropy production term appears.
