摘要: 本文讨论了一类活塞有限时间内的最优运动问题,该活塞设置在气缸中,气缸内含有理想气体工质,伴有泵入热流率f(t),而与一热槽以q∝Δ(T-1)传热规律耦合。求出了获得最大功的活塞最优运动规律,并给出了一些应用实例。

Abstract: This paper discusses the optimal motion of a piston fitted to a cylinder containing an ideal gas pumped with given with a given heating rate f(t)and coupled to a heat bath in the case of heat-transfer law q∝Δ(T-1)for a given finite amount of time. The optimal motion which maximizing the expansion work is obtained. Some applications of the optimal motion are also given.
