| 摘 要： | 发展了一种元系统的热力学，用微分拓扑的方法，仅从热力学第一定律出发，就证明了元系统的热力学温度函数和熵函数的存在性，导出元系统的热力学基本方程，其结果可推广到平衡态和非平衡态的宏观系统。文中也讨论了元系统热力学应用于铁电、超导等系统的热力学的可能性。

| Abstract: | Thermodynamics for elemental system has been developed.With the method of differential topology,on the basis of the first law of thermodynamics only,the existemces of entropy and thermodynamic temperature functions in elemental system have been proved.From this,the basic equations of thermodynamics of elemental system.Its results can be extended into macroscopic systems in equilibrium state and non equilibrium state.The possibility of its applying to the thermodynamics on ferroelectric and superconductive systems has been discussed. |
