摘　　要：使用传统的磁共振实验方法观测气体原子的磁共振信号是很困难的 ,因而目前采用光抽运方法和光探测法对磁共振信号进行检测 ,从而提高了测量的灵敏度 ,但是测试中出现的光抽运信号对实验的现象有干扰。介绍和分析光抽运的原理及其对光磁共振实验中扫场法的影响 ,并提出判别这种影响的方法。It is difficult to observe the signal of magnetic resonance of gaseous atom by using traditional method. Recently optically pumped method and optically of magnetic resonance. But the optically pumped signal appearing in the experiment interferes with the experimental phenomena. This text introduces and analyses the principle of optical pumping and it’s influence of sweep the law of field in the experiment which named optical magnetic resonance. The text advances effective methods of distinguishing the interference.
