摘　　要：在弱磁测量技术当中,往往需要在一定的工作空间区域内获得稳定的磁场。光泵磁强计具有高灵敏度、高分辨力的优点。主要介绍使用光泵磁强计补偿地磁感应温度的原理、设备组成及实验。根据锁相环原理,利用Cs光泵磁强计和线圈系统把地磁感应强度的波动补偿到小于0.1nT,可以获得稳定度很高的恒定磁场空间。恒定磁场空间可以用来校准磁通门磁强计和其它磁传感器。A DC magnetic work area is required in the technology of weak magnetic induction intensity measurement. The optical pump magnetometer has the advantage of high sensitivity and resolution . The principle, device composition and experiment for earth's magnetic induction intensity compensation by Cs magnetometer are introduced. Earth's magnetic induction intensity fluctuation is compensated less than 0.1 nT by Cs magnetometer and coil based on the principle of phase locked loop. The DC magnetic field area is intended for calibration of flux-gate magnetometer or other magnetic sensors.
