我们讨论了非平衡朗之万动力学的简单情况下的波动关系。特别是，我们表明，接近非平衡稳态与非零概率电流，这些关系减少到一个修改后的版本的波动耗散定理。后者可以解释为在参考系中以概率流确定的平均局部速度运动的类平衡关系。
We discuss fluctuation relations in simple cases of non-equilibrium Langevin dynamics. In particular, we show that, close to non-equilibrium steady states with non-vanishing probability currents, some of these relations reduce to a modified version of the fluctuation-dissipation theorem. The latter may be interpreted as the equilibrium-like relation in the reference frame moving with the mean local velocity determined by the probability current.
