【摘要】 理想气体系统是热力学研究的一种典型模型,通过研究理想气体系统,可以得到真实气体的一些主要性质。用统计物理学观点和热力学基本关系式,研究理想气体系统中宏观物理量的涨落及涨落关联函数,进而说明热力学系统宏观量的涨落与热力学系统的状态方程有关。更多还原

【Abstract】 Ideal gas system is one of the typical models to study thermodynamics. By study the ideal gas system, some properties of real gas system can be forecast. How to use the points of view of statistical physics and the basic thermodynamic equations, the fluctuation expressions of macroscopic physics quantity and the fluctuation correlation functions to obtain the ideal gas system have been studied. Furthermore, it has explains how the fluctuation of macroscopic physical quantity relates with the equation of state of the thermodynamics system.更多还原
