摘　　要：分析了地磁观测室周围建筑物的拆建、分量仪的倾斜、磁暴等几种外界因素对地磁场观测值的影响,发现其形式各不相同。并对前两种因素引起的变化运用公式进行了计算改正,以确保观测数据的准确,为地震预报提供有价值的资料。Based on analysis of some external factors, such as building removing and constructing around the observation room, inclination of component apparatus, magnetic storm ect. , effecting on geomagnetic filed observation, it is found that these effects are different. The corrections are made by using some formulae for variations caused by the first two factors, to make observed data more accurate and to provide useful data for earthquake prediction.
