摘要: Sheehan [Phys. Rev. E 57, 6660 (1998)] recently discussed the possibility of establishing a dynamically maintained, steady-state pressure gradient in gas filling cavity. In this Comment it is pointed out that gradients such system, if attainable laboratory, could be used to violate second law thermodynamics.
