The motion of an adiabatic piston under dry friction is investigated to clarify the roles of dry friction in nonequilibrium steady states. We clarify that dry friction can reverse the direction of the piston motion and causes a discontinuity or a cusplike singularity for velocity distribution functions of the piston. We also show that the heat fluctuation relation is modified under dry friction.
研究了绝热活塞在干摩擦作用下的运动，以阐明干摩擦在非平衡稳态中的作用。我们阐明了干摩擦可以使活塞运动方向反转，并导致活塞速度分布函数出现不连续性或尖点状奇点。我们还表明，在干摩擦作用下热涨落关系会被修改。
