我们研究描述非平衡稳态的朗之万动力学。采用 Oono 和 Paniconi 构建的稳态热力学唯象框架 [Prog.理论。物理。补编。 130, 29 (1998)]，我们发现他们提出的第二定律的扩展形式适用于稳态之间的转变，并且香农熵差与无限慢速运行中产生的多余热量有关。贾辛斯基工作关系的广义版本在我们的理论中发挥着重要作用。
We study Langevin dynamics describing nonequilibirum steady states. Employing the phenomenological framework of steady-state thermodynamics constructed by Oono and Paniconi [Prog. Theor. Phys. Suppl. 130, 29 (1998)], we find that the extended form of the second law which they proposed holds for transitions between steady states and that the Shannon entropy difference is related to the excess heat produced in an infinitely slow operation. A generalized Version of the Jarzynski work relation plays an important role in our theory.
