摘　　要：研究了依赖于时间和强度耦合J-C模型中原子的偶极压缩现象。并详细讨论了原子与腔场以时间脉冲形式耦合时,脉冲宽度和腔场强度对原子算符压缩的影响。结果表明,在此模型下原子的偶极压缩随时间的演化特性与其他强度耦合模型明显不同,而且可以通过调节脉冲宽度有效控制原子的偶极压缩程度。The properties of the atomic dipole squeezing in the time-dependent and intensity-dependent J-C model are investigated. The effect of pulse width and cavity field intensity on the atomic dipole squeezing is discussed when the coupling of atomic and cavity field is time-dependent. The results show that the time-evolution of the atomic dipole squeezing in this model is obviously different from other intensity-dependent models, and that the degree atomic dipole squeezing can be controlled effectively by regulating the pulse widths.
