非广延热力学中的热力学势和热力学关系

Thermodynamic potentials and Thermodynamic Relations in Nonextensive Thermodynamics

Lina Gu, Jiulin Du

摘要:

在非广延热力学的框架下,利用物理温度和物理压力导出了广义吉布斯自由能和广义吉布斯焓。考虑到物理温度与拉格朗日乘子的倒数之间的差异,研究了一些数学关系。利用广义热力学势,得到了定容热容与定压热容之间的热力学关系,发现它不同于吉布斯热力学中传统的热力学关系。但是,用广义热力学势计算热容的表达式是不变的。

英文摘要:

The generalized Gibbs free energy and enthalpy is derived in the framework of nonextensive thermodynamics by using the so-called physical temperature and the physical pressure. Some thermodynamical relations are studied by considering the difference between the physical temperature and the inverse of Lagrange multiplier. The thermodynamical relation between the heat capacities at a constant volume and at a constant pressure is obtained using the generalized thermodynamical potential, which is found to be different from the traditional one in Gibbs thermodynamics. But, the expressions for the heat capacities using the generalized thermodynamical potentials are unchanged.
