本文提出了非平衡态辐射体系的热力学框架,以光子的能量、光子的有效能、光子的熵、光子的特征温度为基础,把辐射热力学体系分解为边界和辐射场进行描述,给出了非平衡态辐射场中辐射能状态参数的表征式,提出了表征任意指定照射窗口的照射辐射特征温度概念,结合照射辐射强度、照射辐射能量等效温度,表征了辐射场的能量强度、有效能和熵等热力学参数。
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.
