| Abstract: | 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. |
