摘要
地电场和电阻率同场地观测时,电阻率观测会干扰地电场的观测数据发生大幅度变化.本文主要探讨通过曲线拟合的方法消除这种干扰及其它随机干扰,并给出了对实际观测数据处理的结果.
To be observed on same field in same time,telluric observation is interfered by electric current in measuring the apparent resistivity,and the data are changed to square impulse.In this paper,the method of least square fitting which can be used to eliminate this interference and other random interference in telluric data is discussed.The practically processed result is given also.
