本文选取泾阳地磁台2007年FHD-1核旋磁力仪和CB3磁变仪观测数据采用日变幅形态、日均值年变形态、总场21点值年变形态等方法做对比分析。结果表明：两种观测一致性较好,说明数字化仪器观测的数据是可靠的,但是数字化仪器还存在易受外界环境干扰,稳定性不好的问题,需要工作人员按规范调试仪器,认真维护与管理。

This article selects observation data of FHD-I nuclear precession magnetometer and CB3 geomagnetic variometer at Jingyang Geomagnetic Seismic Station in 2007, and makes comparative analysis in terms of the daily amplitude, mean annual change shape, and total intensity magnetic field. The results show that two kinds of observation have good consistency, and digital instrument observation data are reliable, but the digital instrument is vulnerable to external environment interference and is not stable enough, and needs careful maintenance and management.
