| 摘 要： | 本文采用时间演化算符方法和数值计算研究了相干光场与混合态二能级原子相互作用双光子过程中原子的压缩效应．结果表明：原子初始所处的混合态对原子压缩性质有较大的影响，当０．８５＜Ｓ＜１时，会周期性地呈现出短时的原子压缩效应，随着原子初始混合程度的增大，原子越来越远离压缩状态．

| Abstract: | In this paper, the atomic squeezing effects in the two-photon process with two-level atomic mixed-state are studied by means of the time-evolution operator method and numerical calculation. The results show that the squeezing properity of the atom do depend greatly on the atomic initial mixed-state, and the atomic squeezing effect is displayed periodically as 0.85 < S<1; with the increasing of the mixing extent of the atomic initial state, the characteristics of atom is getting far from squeezing state. |

| Keywords: | mixed-state two-photon atomic squeezing initial level population probability |
