固体不极化电极现场实验研究

Experimental Study of Solid Non-polarized Pole on the Spot

本实验是针对以下两个问题进行的:一是深度实验。在同一位置,将电极埋于不同的深度,观察电极埋设在不同深度时,对电场的观测基本没有影响;二是灌水实验。利用自来水和饱和食盐溶液直接灌入电极坑内,观察得知,电极长时间浸泡在水中或盐水中,对电极无明显影响。本实验得出的结论是:在电极埋设完成后,一定要灌水,第一次灌水对电极的影响很大,以后的灌水对电极的影响比较小;给一对电极中的一个电极灌水,对电位差有较大影响;同时给一对电极灌水,对电位差则无明显影响;在一对电极之间灌水,对电位差亦无明显影响。

The test is aiming at the two following problems. (1) Depth test. The poles are buried in different depths. It is known from the observation that basically there is no influence that buried depths of poles to the observation of electric field. (2) Water-pouring test. The running water and saturated salt solution is poured into the pole pits. It is known that there is no obvious influence to the pole when the pole is marinated in the water or the salt solution for a long time. The conclusion obtained in this test is that water must be poured into the pits after the pole is buried. The first water- pouring has large influence to the poles, and smaller later on. The water poured into one pit of one pair of pits will cause bigger influence to the observation of difference of electric potential. The water is poured into both poles at the same time will not cause obvious influence to the observation. The water is poured into the position between one pair of poles will not cause obvious influence to the difference of electric potential.
