利用全量子理论，研究了Tavis—Cumming模型(T—C模型)中运动双原子与二项式光场相互作用系统的两原子纠缠演化特性。计算结果表鳃：两个运动原子之间的纠缠呈现出周期性的演化特性；不同初始状态下，二项式光场系数、原子运动速度对原子间的纠缠演化有显著的影响。二项式光场系数影响原子间振荡频率以及消纠缠持续时间，不影响纠缠演化的周期。随着原子运动速度的增大，原子间的纠缠演化周期逐渐缩短，而纠缠度峰值的大小和振荡频率不变。

The atoms' entanglement character of the moving atoms in tavis-cummings model with the binomial field interacting is studied. The results indicate that the two moving atoms entanglement state appears periodically. The influences of the atomic motion and the parameters of the binomial light field on the atoms' entanglement character are discussed by means of the full quantum theory. The parameters of the binomial optical field has an effect on the entanglement, the frequency of oscillating and the range appearing entanglement phenomenon, but it does not influence periodicity of the entanglement of the evolution. The two atom's speed influence the periodicity of the entanglement of the evolution in the middle state of the optical field. The atom's speed does not influence the value of the entanglement and the frequency of oscillating of the atoms.
