两个埋在土层或基岩内的电极接成通路之后,就有稳定的电流通过测最仪表。这种装置在地震群测队伍中被广泛使用,称之为“土地电”。从电化学和地电学可知,两个电极埋入地层内的通路电流,可以反映电极电位差和地下介质中的电流场。室内试验和现 Two buried in the soil or bedrock electrode connected into the pathway, there is a steady current through the measured instrument. This device is widely used in the earthquake detection team, known as “land electricity.” Electrochemistry and geoelectric can know, two electrodes buried in the formation of the passage current, can reflect the electrode potential difference and the underground medium in the current field.
