摘要
考虑到失谐量和原子初始相干性，给出了任意初态分布的二能级原子与任意单模场相互作用的密度算符间距的一般表达式．着重讨论了一个任意态分布的二能级原子与相干态光场相互作用时失谐量对密度算符间距演化的影响．结果表明：密度算符间距明显地依赖于失谐量的取值．
By considering the detuning and the initial atomic coherence,a general expression of distance between density operators of arbitrary initial states (reference states) is obtained. The emphasize is put on the influence of detuning on the evolution in the interaction of a two\|level atom of arbitrary initial states with the coherent field. The results show that the distance between density operators is obviously dependent on the value of detuning. PACC: 4250
