中文摘要：
对铷原子（87 Rb）蒸汽中的法拉第旋转、光学偏振自旋转以及二者的叠加旋转效应进行了理论和实验研究．对三种情况下旋转现象建立了简单而有效的理论模型．实验中把铷原子泡置于自行设计的磁屏蔽腔内，以屏蔽地磁场的影响．实验选择。87RbF=2→F’=3能级D2跃迁线并采用零多普勒光谱实验结构消除多普勒展宽对实验光谱的影响．实验中分别观测到了三种旋转现象，实验结果与理论模拟结果非常符合．
英文摘要：
We theoretically and experimentally study the effects of Faraday rotation, optical polarization of self-rotation, and their overlap- ping rotation. In our theoretical simulation, we set up a simple and effective theoretical model for the three kinds of rotations. In our experiment, the atomic vapor is placed in a magnetic shielding cavity to shield the earth magnetic field. Doppler-free spectrum config- uration is used and the F = 2 → F＇= 3 transition of STRb D2 line is chosen. We observe the three kinds of rotations, separately. Experimental results and theoretical simulations are in good agreement.
