中文摘要：

通过数值计算的方法,研究了两原子依次通过双模纠缠场时量子关联的产生,讨论了双模场的初始纠缠对两原子的纠缠和量子失谐的影响。结果表明：双模场的初始纠缠为零时,两原子的纠缠和量子失谐为零,初始双模场的纠缠不为零时,纠缠和量子失谐不为零并随时间演化;初始双模场的纠缠越大,两原子的纠缠和量子失谐越大;原子的两种初态（｜e1,e2〉,｜g1,g2〉）下,纠缠和量子失谐产生的阈值时间与双模场的纠缠度没有关系。

英文摘要：

The birth of quantum correlation of two atoms going through a bimodal cavity one after another was investigated by means of numerical analysis method,and the effects of initial entanglement of bimodal cavity on entanglement and quantum discord were analyzed. The results showed that, when the initial entanglement of the bimodal cavity is zero, the entanglement and quantum discord of two atoms is zero. While the initial entanglement of the bimodal cavity is nonzero, the entanglement and quantum discord of two atoms is also nonzero and evolve with the time. The larger of initial entanglement of bimodal cavity is, the larger of entanglement and quantum discord of two atoms is. The threshold time for creation of the entanglement and quantum discord has no relation to entanglement of bimodal cavity in the case of [ e1 ,e2 ）, g1 , g2 ）
