| 摘 要： | 通过对广州地磁台环境干扰源的监测，计算与分析得到：（1）不同时期产生的二个干扰源对地磁台1号墩磁场总强度测值的迭加影响为－25nT，与多台资料对比结果一致。（2）地磁台1号和5 ，1号与干扰源场区外Ⅰ号比测墩测得的磁场总强度、水平强度及垂直强度之差随时间的变化不明显，故认为广州地磁台环境干扰源目前尚属稳定。

| Abstract: | By surveying, calculating and analysing the environmental interference source in Guangzhou Magnetic Station, two conclusions are drawn showing in the following; 1, two interference sources which occurred at different period are influenced on the magnetic field of NO. 1 Pier and the value of its total magnetic intensity is -25nt, which shows no difference by comparing the results of the data in many stations. 2, By monitoring the piers between NO. 1 and NO. 5, NO. 1 and NO. 1 outside the field of the interference source, the difference between the total magnetic intensity., horizontal intensity and vertical intensity is not clear in variation with time. Therefore, the environmental interference source is thought to be stable at the present time. |
