根据离子溶液电化学的基本性质和稳定电流场的基本理论，通过理论计算和物理模拟实验，指出：离子在外电场作用下，由所在地点迁移至接收电极所需时间与多种因素有关，当外界条件一定时，加大供电电流强度可减少接收时间；离子淌度值很小，由实测时量曲线计算出的ｕｉ值，一般不超过几个ｃｍ２·ｈ－１·Ｖ－１单位，因此欲提取深部离子，即使在最有利条件下也是非常困难的；由不同供电电流强度测出的时量曲线，计算得到的淌度值是相等的，因此改变供电电流强度并不能改变离子淌度值，但当围岩介质的颗粒度较大时，可使离子淌度值变大；离子的迁移质量与供电电量Ｑ＝Ｉ·ｔ成正比，因此在供电电流强度不变的条件下，采用间断供电方式可取得与连续供电相同的结果；通过浅部已存在的离子晕，用电提取法可以发现深部隐伏矿体。
According to the basic properties of the electrochemical solution and the basic theory of stable current field, theoretical calculations and physical simulation experiments show that the time required for the ions to migrate from the site to the receiving electrode depends on many factors. When the external environment When the condition is certain, increasing the intensity of the supply current can reduce the receiving time; the ion mobility value is very small, and the value of ui calculated from the measured time curve generally does not exceed a few units of cm2 · h-1 · V-1 Extraction of deep ions is very difficult even under the most favorable conditions; the mobility values calculated from the time-curves measured with different supply current intensities are equal, so changing the supply current intensity does not change the ion mobility value, However, when the grain size of surrounding rock is large, the value of ion mobility can be increased. The migration mass of ions is proportional to the power supply Q = I · t. Therefore, under the condition of constant supply current intensity, Way to get the same result with the continuous power supply; through the existence of superficial ion halo, electric extraction method can be found deep buried ore body
