| Abstract: | A thermodynamic framework is proposed for the non-equilibrium radiation system. On the basis of the energy,the available energy,the entropy,and the effective temperature of photon,the boundary and the field of the radiation thermodynamic system are described.The expressions of state parameters are presented for the radiation energy in the non-equilibrium radiation system.The effective temperature of incident radiation is proposed for a certain incident area. Combined with the radiant intensity and the effective temperature of incident radiation,the expressions of the energy intensity,the available energy,and the entropy are developed for the radiation field. |
