Abstract
This article analyzes preliminarily the data of reference background noise,which is chosen from GM4-1 fluxgate magnetometer instrument and GM4-2 fluxgate magnetometer instrument during the year of 2009 to 2013 at Hongshan Seismic Station. The result shows that the reference background noise of two instruments annual variation trend is consistent,and magnetic declination component changes with the seasons obviously,horizontal component and vertical component is not obvious. In addition,the background noise GM4-2 fluxgate magnetometer′s each component is more than that of GM4-1 fluxgate magnetometer instrument,which is caused by itself through the analysis by comparison.关键词
