在人工电流场—磁场或激发场作用下,具有不同电化学性质的岩石或矿石,由于电化学作用将产生随时间变化的二次电场(激发极化场)。这种物理化学作用称为激发极化效应。它包括电子导体的激发极化效应和离子导体的激发极化效应。
本文还得到二极装置和错层条件下的负激发极化效应。
On the other hand, we have the negative IP effect on two electrode array and over mixed layers.
这些聚集在粘土矿物界面上的电荷就产生了激发极化效应。
This charge, which accumulates mainly at interfaces between clay minerals, is responsible for the IP effect.
本文介绍了在压应力作用下观测岩石失稳破裂前激发极化效应的实验方法和主要结果。
This paper introduced the experimental method and main results of induced polarization effect observed before the rupture of the instable rocks under the action of compressional stress.
