摘要
阳原台地电阻率观测受外界影响非常严重,因而严重影响了观测资料的精度,使资料质量大大降低。本文通过实验和研究,找到了影响资料观测精度的因素:(1)漏电;(2)电极老化;(3)稳流源输出不稳定;(4)降雨;(5)风扰,并分别加以排除。
The earth resistivity observation in Yangyuan Seismostation is affected seriously by environment factors, and its observational precision reduced greatly. Through test and research, the interferences are found out and eliminated. The interferences are: (1) leakage of electricity; (2) electrode ageing; (3) instability of current regulator; (4) rain; (5) wind.
