摘　　要：介绍了光磁共振实验装置的各磁场线圈,分析了光磁共振实验中抵消地磁场垂直分量传统方法的缺陷,利用垂直磁场对磁共振信号的影响,提出了一种重复性较好的抵消地磁场垂直分量的方法,减小了传统实验方法产生的误差.这种方法也可用于测量地磁场垂直分量的大小.The coils of magnetic field in the optical magnetic resonance experiment were introduced, and the shortcomings of the traditional methods in offsetting the vertical component of the geomagnetic field were analyzed. Based on the influence of the vertical magnetic field on the magnetic resonance signal, a method of offsetting the vertical component of the geomagnetic field with good reproducibility was proposed to reduce the error caused by traditional experimental methods. This method could also be used to measure the vertical component of the geomagnetic field accurately.
