摘要
本文为研究电磁场作用下的空间小同热力学性质,对平衡态热力学系统以及非平衡态热力学系统进行研究。对于电磁场作用下的平衡态热力学系统,通过能量公理介质电场能量微分公式以及热力学能微分式引进电磁场参量,结合辅助函数得出微分关系,得出平衡态热力学系统特性。对非平衡态热力学系统重新推导非平衡态热力学的平衡方程,结合局域平衡假设得出熵平衡方程,并在唯象理论基础上得出非平衡态热力学系统特性。
In order to study the spatial and thermodynamic properties of electromagnetic fields,the equilibrium thermodynamic system and nonequilibrium thermodynamic system are studied. The equilibrium thermodynamic system under electromagnetic field,the energy field formula and differential energy axiom medium thermodynamic energy differential introduced electromagnetic field parameters,combined with auxiliary function to draw the differential relation,derive the equilibrium properties of the thermodynamic system. The nonequilibrium equilibrium equations of non-equilibrium thermodynamics are rederived,and the entropy balance equation is derived based on the local equilibrium assumption,and the non-equilibrium thermodynamic system characteristics based on the phenomenological theory are also obtained.
