中文摘要：

借助于数值计算方法，研究了热光场与运动二能级原子相互作用系统的保真度，讨论了原子的初始状态、运动速度及光场的初始平均光子数对系统保真度的影响．结果表明原子初始状态、运动速度及光场的初始平均光子数都对保真度有不同程度的影响．

英文摘要：

By means of numerical methods, we studied the fidelity of the system which contained a moving two-level atom and the thermal light field. The impact of different initial states, atom velocity and initial mean photon number of light field were discussed to the fidelity of quantum states. The result showed that atom initial state,atom velocity and the initial mean photon number can make different influence to the fidelity of the system.
