摘　　要：研究了Berthelot流体的热力学性质.导出了单原子Berthelot流体Helmholtz自由能、熵、吉布斯函数、内能和焓;求得了Berthelot流体两相共存的的参数解,并用参数解讨论了Berthelot流体的相图和热力学量在临界点的行为及其相关性质.本文的研究为符合Berthelot流体的物质提供了热力学及其相变的解析理论.This paper is devoted to the study of thermodynamic properties on the Berthelot fluid.The Helmholtz free energy,entropy,Gibbs function,internal energy and enthalpy of monoatomic Berthelot fluid are derived;the parametric solutions of the Berthelot fluid two coexisting phases are obtained,and phase diagrams,thermodynamic behaviors near the critical point and associated properties are discussed by using the parametric solutions.The study provides analytic theory of thermodynamics and phase transition for substances satisfying the Berthelot fluid.
