绥化地电阻率趋势性下降原因探讨
REASERCH ON THE CAUSE OF TENDENCY DROP OF SHUIHUA APPARENT RESISTIVITY
【摘要】 通过利用绥化地震台地电阻率、降水、地下水位的观测资料进行相关分析,对观侧仪器、供电线路、观测线路、极板老化进行实验,认为1980年以来绥化地电阻率趋势性下降是由观测仪器本身的零漂所引起。
【Abstract】 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.
