摘　　要：光泵磁共振是利用光抽运效应来研究原子超精细结构塞曼能级间的磁共振.根据光磁共振原理,利用光泵磁共振实验对共振信号进行检测,观测水平磁场和垂直磁场对共振信号的影响.分别通过两种方法测量出地磁场的水平分量和垂直分量,进而将二者合成,得出芜湖地区地磁场强度大小.The optical pumping magnetic resonance is an experiment designed for studying the super-fine structure of atoms applying the optical pumping effect. According to the principle of optical-magnetic resonance, we use optical pumping magnetic resonance experiment to observe of the resonant signal and to detect the influence of the horizontal magnetic field and the vertical magnetic field to the resonant signal. This paper measures the horizontal component and vertical component of the magnetic field respectively through two kinds of methods. At last, the terrestrial magnetic field of Wuhu is determined by composing the two components.
