利用全量子理论，研究了多光子Jaynes-Cummings模型中与 Glauber-Lachs态相互作用的混合态原子的信息熵压缩。讨论了相干平均光子数、热平均光子数、跃迁光子数、原子初态参量对原子信息熵压缩的影响。结果表明原子信息熵X分量没有熵压缩性质；相干平均光子数取值适当时，原子信息熵Y分量呈现熵压缩效应；热平均光子数、跃迁光子数会破坏原子信息熵Y分量的熵压缩效应；原子初态参量对原子信息熵Y分量能否呈现熵压缩效应没有决定性作用；伴随双光子跃迁时，原子的熵压缩因子的时间演化曲线呈现周期性。

The information entropy squeezing properties of the atom interacting with the Glauber-Lachs state in multi-photon Jaynes-Cummings model are studied by means of the full quantum theory.The in-fluences of the mean number of the coherent photons,the average number of the thermal photons,the number of the transition photons and the atomic initial state on the information entropy squeezing of the atom are discussed.The results indicate that there is no entropy squeezing in the X component of infor-mation entropy of the atom at any instant of the time evolution of the system.But there exists an entro-py squeezing in the Y component of information entropy of the atom during the time evolution when the mean number of coherent photons takes an appropriate value.The mean number of thermal photons and the number of the transition photons have a destructive effect on theY component of information entropy of the atom.The atomic initial state has no effect on the entropy squeezing in the Y component of infor-mation entropy of the atom.If the number of the transition photons equals to two,the time evolution of the entropy squeezing factor appears periodic change.
