摘　　要：本文研究了无旋波近似下双光子Ｊａｙｎｅｓ－Ｃｕｍｍｉｎｇｓ（Ｊ－Ｃ）模型中原子的偶极压缩与旋波近似下的情况比较，结果表明：原子偶极压缩效应因虚光子过程而变化，并分析了压缩程度与光场频率。In this paper the atomic dipole squeezing in the two-photon Jaynes-Cummings model without the rotating-wave approximation has been discussed. From the comparison between the case with RwA and that without RWA,it has been shown that the atomic dipole squeezing is dependent on the virtual-photon processes. Moreover. the relationship between the squeezing degree and the field frequency. the meam photon number, and the atom-field coupling contant has been analyzed .
