摘　　要：用全量子化理论 ,研究了与运动二能级原子相互作用的双模量子化光场的量子特性 ,分析了场模结构对平均光子数 ,单模二阶相干度 ,两模间的相关性的影响 .研究结果表明 ,随着场模结构参量的增大 ,平均光子数回复周期变短 ,振荡加剧 ,在崩塌区域内振荡出现分裂 。The quantum properties of the two-mode quantized light field interacting with a moving two-level atom are studied by means of quantum theory. The influence of the parameter of the field-mode structure on the average photon numbers, the degrees of second-order coherence and the degree of interbeam second-order coherence is discussed. The study shows, with an increase of the field-mode structure, the revival period of the average numbers becomes short, oscillation becomes intense and oscillating curve shows split in the field of collapse. At the same time, atomic move has an obvious influence on the degrees of second-order coherence of light field.
