论文摘要

在过度阻尼系统的热力学的推导中,人们忽略了动能的贡献,因为速度是一个缓慢的变量。在本文中,我们表明需要在热分布的计算中存在动能,才能在不足和阻尼过度的病例之间具有正确的对应关系,这意味着在这些系统的热力学中不能完全忽略速度。我们通过详细研究动能对三种不同系统的影响,即谐波电位,对数电位和任意的非等温过程。

In the derivation of the thermodynamics of overdamped systems, one ignores the kinetic energy contribution, since the velocity is a slow variable. In this paper, we show that the kinetic energy needs to be present in the calculation of the heat distribution to have a correct correspondence between the underdamped and overdamped cases, meaning that the velocity can not be fully ignored in the thermodynamics of these systems. We do this by investigating in detail the effect of the kinetic energy for three different systems, the harmonic potential, the logarithm potential, and an arbitrary non-isothermal process.
