Xiao Chen · Seismological Research of Northeast China · 2003
This paper introduced the results of the correlation analysis using the observational data of the apparent resistivity,precipitation,ground water level in Shuihua seismic station and of the test for the observation instrument,supply line,observation line,plate ageing.It was considered that the tendency drop of the apparent resistivity in Shuihua seismic station since 1980 is caused by the instrument's zero drift.
