摘　　要：利用T-C模型研究了耦合二能级原子与相干态光场相互作用系统中场熵的演化规律,数值计算结果表明:场熵的演化受原子间耦合强度和光场初始平均光子数的变化的影响.The entropy evolution of the field in interaction of two coupling two-level-atoms with coherent state is studied. Using Tavis-Cummings model, the influences of coupling constants between atoms and intial mean photon number of field on entropy evolution of the field is studied. The results obtained using the numerical method show that with decreasing of coupling constant between atoms and increasing of intial mean photon number of field, The entropy evolution of the field is getting stronger.
