摘　　要：研究了几种不同矿物成分和孔隙液的土柱在压应力作用下，两端面间产生电位差的现象。该现象表明此电位差（或其增量）与应力（或其增量）成正比例，这种电位差被论证就是流动电位（差）。The potential difference is depended on compressive stress between two top planes of soil column containing different mineral and pore water. This phenomenon is studied and the conclusion is obtained that the potential difference or its increment is direct proportional to the compressive stress or its increment. The nature of the potential difference is the difference of streaming potential.

关 键 词：应力 电位差 流动电位 土柱
