摘要
为使用铅电极替代不极化电极,以解决滨海地区大地电场观测系统稳定性差的问题,先后开展了浅埋的铅电极与不极化电极的大地电场对比观测,以及深埋铅电极与浅埋铅电极的对比观测试验。结果表明:铅电极与固体不极化电极的观测数据在短期内有较好的一致性;深埋铅电极的大地电场观测资料在长期稳定性上优于固体不极化电极;而观测数据的内在观测质量也高于浅埋铅电极。
In order to substitute non-polarizable electrode with lead electrode and solve the stability problem of earth electric field observation in seashore area, we have performed two kinds observational comparison, which is shallow burying lead electrode with non-polarizable electrode and deep burying lead electrode with shallow burying lead electrode. The results show that the observation data of lead electrode are consistent with that of non- polarizable electrode in short period, and the stability of the data from deep burying lead electrode excels solid non-polarizable electrode, and its inherent quality also excels shallow burving lead electrode.
