分析了依赖强度耦合Jaynes-Cummings模型在初始相干光场较强的情况下(1)原子和场退耦合的条件，详细地研究了对于不同的原子初态原子和场的各种disentangled-states的确切表达式及其演化的周期性，并且用密度算符间的距离对原子和场的这些disentangled-states及其演化进行了充分的论证.In this paper, the disentanglement conditions in the intensity dependent coupling Jaynes-Cummings model are derived for large initial field (1). The atomic and the field disentangled-states are investigated in detail for varied initial atomic state, these disentangled-states and the periodicity of the dynamical evolution are examined by the distance between density operators.
