摘　　要：本文主要讨论热微扰对热力学系统的影响。从刘维方程出发,运用统计物理中局域平衡的方法导出热力学系统对热微扰的响应的普遍适用的关系式,及涨落耗散定理,并应用于具体的耗散过程,得到正确的结果。In this paper we deal mainly with the influence of thermal perturbation on thermodynamic systems. Starting from the concept of local equilibrium in statistical physics, and using the Liouville equation, we have discussed the response of thermodynamic systems to thermal perturbation, and derived the fluctuation-dissipation theorem. We have also applid them to a variety of systems and obtained correct results.
