摘　　要：本文研究了任意初态的双光子Jaynes-Cummings模型的一般演化规律,着重于分析初始原子相干性对辐射场压缩行为的影响,作为例子,讨论了一个任意初态的二能级原子与真空态和相干态光场相互作用时辐射场的压缩.数值计算了各种条件下辐射场压缩的时间演化.In this paper, the general evolution laws of the two-photon Jaynes-Cummings model with initially arbitrary states have been investigated. And the emphasis is put on the influenec of the initial atomic coherence on the squeezing of radiative field in the two-photon Jaynes-Oummings model. As an example, the squeezing of the field in the interaction of a two-level atom of arbitrary initial states with the vacuum and coherent field is studied, and the squeezing of the field under various conditions has been calculated numerically.
