摘　　要：借助于数值对角化方法，研究了非旋波近似下Ｊ─Ｃ模型中原子的压缩效应，结果表明，在近可积区能观察到此种效应及其周期衰变与回复现象。By virtue of a numerical method of truncating an infinite matrix to finite order, we have investigated the squeezing properties of atom in the Jaynes Cummings (J C) model. Numerical results have shown that dipole squeezing and quantum collapse revial phenomena can be observed in the cases rather close to integrable limits, while these features disappear in the cases far from these limits.
