摘　　要：研究了非旋波近似下双模压缩真空场与二能级原子相互作用系统的纠缠特性,着重讨论了虚光场效应对系统纠缠特性的影响。The entangle properties in a system of two mode squeezed vacuum field interacting with a two level atom are studied without the rotating wave approximation by means of quantum theory, and the influences of the virtual-photon process on the entangle properties are discussed emphatically.

关 键 词：非旋波近似 双模压缩真空场 纠缠特性 附加“熵振荡”
