| Abstract: | ± 660 kV DC transmission demonstration project which is from Ningdong to Shandong had been tested and run,which influences geomagnetic observation of many stations in Shandong Province.Therefore,the analysis of influence mechanism of geomagnetic observations by high-volt age DC,the calculation of the impact of magnitude and the proposal of the geomagnetic pretreatment methods （such as comparison of curve shape、the principle of recognization of interference、the dmissetermination of the interference amplitude and so on） offered some beneficial thoughtway to the influence of direct current transiting on geomagnetic observation in our country. |
