| 摘 要： | 通过试验，认为地电供电系统对地磁观测的影响主要是来自供电导线产生的磁场，其强与公式Ｈ＝１／１０．２Ｉ／ｒ计算结果基本相符。而地下电流产生的磁场是很弱的，这对避免和减小其影响提供了新思维。

| Abstract: | By means of testing, it is concluded that the influence of the power-supplied system of earth electricity on the geomagnetic observation is mainly resulted from the magnetic field induced by the power-supplied conducting wires. Its intensity is basicallycoincident with the calculated value by using the formula H =1/10 ?I/r; while the intensity of magnetic field caused by the underground current is quite weak, provided a new concept for avoiding and reducing such an influence. |
