摘　　要：FHD分量质子磁力仪利用补偿测量方法(Nelson方法)测量水平分量,利用偏置测量方法(Sensor方法)测量磁偏角的相对变化,由于装置存在误差和长期漂移,会对观测数据的长期稳定性产生影响,为了消除或校正这些影响,对观测误差进行分析,提出对相关影响因素进行校正的方法和步骤,并提出观测系统漂移量的判断和估算方法,以及在标定过程中应注意的问题,对FHD质子磁力仪的标定效果和质量起到较好的监控作用。FHD vector proton magnetometer use compensation measuring method （ Nelson method ） and a bias measuring method （Sensor method） for measuring horizontal vector and magnetic declination relative changes. However, instrumental error and long-term drift will have effects on the long-term stability of observation data. In order to eliminate or correct the effect, this paper analyzes the observation error and puts forward a correlative {actors correction method and steps, and also puts forward the forward observa- tion system drift amount judgment and estimation methods, as well as the problems in the calibration process that should be paid attention to. These measures have a great monitoring effect on the FHD proton magnetometer calibration effect and quality.
