摘　　要：研究Kerr介质中,非旋波近似下两个二能级原子与单模光场相互作用的平均光子数的时间演化规律,讨论了Kerr效应和虚光场效应对系统光子统计演化特性的影响.结果表明虚光场的影响使系统出现量子噪声,光场频率ω、Kerr介质常量μ和原子间耦合系数g的增大都将使量子噪声减小;原子间耦合系数g和Kerr介质常量μ的增大使光子统计演化的拉比振荡的振幅变小.In this paper, the evolution ot the mean photon number in the system of two two-level atoms interacting with a single mode light field in the Kerr medium is studied by C-RWA. The influences of Kerr effect and virtual photon field effect on the photon statisieal properties are also discussed. It has been shown that： the quantum noise appears under C-RWA： the quantum noise becomes weak while ω, g and μ increase：the amplitude of Rabioscillation decreases while g and μ increase.
