图2 圆柱形原子气室与线圈位置示意图.FID线圈对称地放置于柱面两侧，射频信号作用于y轴方向，泵浦光方向和主磁场方向均与z轴平行

Fig. 2 The schematic diagram represents the position of the cylindrical atomic chamber and the coils. The FID coils are symmetrically placed on both sides of the cylindrical surface. The RF signal is applied in the direction of the y-axis, and the direction of the pumping light and the main magnetic field are both parallel to the z-axis
