摘　　要：利用全量子理论 ,研究了非旋波近似下两个二能级原子与单模光场相互作用过程中受激场场熵的演化规律 ,通过与旋波近似下的相应结果进行比较 。In this paper,the field entropy evolution in the system of two two level atoms interacting with a single mode light field is studied by means of the quantum theory without rotating wave approximation Compared with the result of rotating wave approximation,the influences of the virtual photon process on the evolution of field entropy is also discussed
