本文对电提取方法中作用条件一致问题进行了理论探讨和分析。认为分道电流的大小是地下综合因素的总体反映 ,同某一具体种类的提取物含量间不存在线性空间对应关系。因此 ,分道“电流调节一致”的技术措施并不能保证、甚至有碍各个分道在电提取过程中作用条件的一致。并指出 ,过程作用条件一致的重要因素决定于电场电压 In this paper, the theoretical analysis and analysis of the problem of the same action condition in electric extraction method. It is believed that the size of the shunt current is an overall reflection of the comprehensive factors in the subsurface and does not have a linear spatial correspondence with the content of the extract of a particular species. Therefore, the technical measures of “uniform current regulation” of the lanes can not guarantee or even impede the consistency of the conditions of the functions of the lanes in the electric extraction. It is also pointed out that the important factor of consistent process conditions depends on the electric field voltage
