电场差分法中的干扰电场形成及消除方法

The Formation Principle and the Eliminaion of Disturbing Electric Field in Electric Field Differential Method

电场差分法在实际应用中受到大地电磁场、自然电场、极化电位及人文电场等的影响。文章全面分析和总结了这些干扰电场的形成原因及其特征，在此基础上给出了消除这些干扰电场的方法原理及其应用效果。

The applications of electric field differcncial method are affectedby many unwanted distur bing electric field such as spontaneous potential, polarization potential, electromagnetic field and industry noises. Based on the formation Principle and the characteristics of thesedisturbance, this paper put forward some of the means of their elimination and the result of applicaton.
