摘　　要：讨论了考虑原子间的相互作用的二能级原子的玻色-爱因斯坦凝聚体(BEC)与双模压缩相干态光场相互作用系统中光场的正交压缩性质.结果表明:压缩深度与初始压缩因子密切相关,而压缩持续时间则与多个因子有关.When considering the interaction between atoms, the properties of quadrature squeezing of light field of two-model squeezing coherentlight field interacting with atomic BoseEinstein condensate is discussed. The results show that maximum depth of squeezing is closely correlated to the initial squeezing parameter of light and that duration is determined by several factors.
