摘　　要：对多年的观测资料进行综合对比分析，分别得出了磁法仪器与电法仪器观测地磁场水平强度（Ｈ）各自的精度、稳定性及两者之间一致性等结果。这对各地磁台采取不同观测仪器以便寻求最佳观测组合形式。The 1994~1996 observational data from Urumqi geomagnetic station are comprehensi vely analysed in this paper,and the accurracies and stabilities that magnetograph and electrograph observe the horizontal geomagnetic field strength(H) are gotten and compared.This will supply reference for geomagnetic stations obtaining best combination of different observational instrument and related departments developing digital geomagnetic observational system.
