我考察了在最近的一部著作中指出的“物理不一致”，因为它源于对操纵系统的涨落关系中出现的表达式的使用，例如雅金斯基等式。我认为这些不一致是虚幻的，因为从这个关系式中获得的自由能差的表达式中出现的“任意参数”实际上具有直接而简单的物理解释，与执行操作所需的物理设置相联系。
I examine the ‘physical inconsistencies’ pointed out in a recent work as deriving from the use of the expression which appears in fluctuation relations for manipulated system, such as Jarzynski’s equality. I show that these inconsistencies are illusory, since the ‘arbitrary parameters’ that appear in the expression of the free-energy difference obtained from this relation turn out to have a direct and simple physical interpretation connected with the physical setup needed to perform the manipulation.
