摘　　要：选取郑州台2002年地磁相对观测D、Z分量资料,对同期数字化和模拟观测数据采用日变形态、趋势分析、差值分析、极值时间等方法作对比分析。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,用来代替模拟仪器是可行的,但因数字化仪器还存在观测数据突跳的问题,尚需作进一步的改进和完善。Based on D and Z component data of relative geomagnetic observation of Zhengzhou Geomagnetic Station, comparisons between digital data and analog data in the corresponding period by the means of daily variation shape, trend analysis, difference analysis and extremum time are carried out. The result shows that the two recording systems have good consistency. It is indicated that the date produced by digital instrument is reliable and that it is feasible to replace simulating instrument with the digital one. On the other hand, digital instrument observation still has the problem of sudden jump in data, needed improving and perfecting further.
