| Abstract: | The interference of precuros observation at Golmud Seismic Station from 2008 to 2012 is analyzed.It is believed that the main interferences come from lighting,air mutations,and human disturbances,such as closing the discharge mouth of artesian wells,equipment maintenance,zero setting and monthly calibration,observation system interference include the various causes,power supply and restart the instrument,and power on impact,equipment failure,line interference. |
