| 摘 要： | 利用推广的Ｊ－Ｃ模型，研究了理想环形腔中原子的质心运动对原子算符压缩效应及腔场统计特性的影响，当腔场初始处于相干态时，研究结果表明：原子的质心运动将影响光场的光子数分布和光场处于相干态的时间及光场的场熵演化，质心动量的波包越宽，影响越明显；反过来，腔场将影响原子质心的动量分布和原子算符的压缩效应，原子质心运动的波包越宽，对压缩效应的影响越明显。

| Abstract: | The effect of moving mass center on atomic dipole squeezing and statistical properties of cavity field have been studied. The calculated results show that the moving mass center will affect photon number distribution,the field coherence, and evolution of the field entropy, the wider the wave packet is, the larger the effect is. In contrary, the cavity field will also affect momentum distribution and atomic dipole squeezing effect,the wider the wave packet of moving mass center, the more obvious the squeezing effect is. |
