Xuechuan Li · Earthquake Research in Sichuan · 2008
We make an analysis on the eatrh tide observation data of DZW digitalized gravity meter in Guza Seismic Station,calculate the inner precise of observation,study the original documents and wave-gram,discuss the stability of gravity meter,the relative noise level,and the interfere factors.The connection between observation and earthquakes is discussed briefly.
