摘　　要：研究了旋波近似下级联型三能级原子与单模相干场相互作用的场熵演化规律 ,讨论了原子与场模间的耦合系数和初始场的平均光子数对场熵演化的影响 .In this paper, the evolution of the field of the interaction between three-level cascade atom and the single mode coherent field under the Rotating-Wave Approximation (RWA) has been investigated. The influences of the initial mean photon number n and of the atom-field coupling constant λ on the field entropy have been discussed.
