摘要
天然电场选频法是以天然大地电磁场作为工作场源,测量天然电磁场在地面上产生的电场分量,研究地电断面的电性变化,进行找水或解决其它地质问题的交流电勘探方法。它具有抗工业游散电流强,轻便快捷的特点,深受广大物探人员的重视,特别有利于城市物探工作的开展,值得推广应用。
The self--potential frequency method is an A.C.electric prospecting method which uses the natunal telluric electro-magnetic field as the source of electric potentiahl,and measures the ground potential component of the natural elector -magnetic fielcd to investigate the variation of electric properties of the geo-e lectric section beneath the ground, so as to find water resources or solve other geologic problems.It is characteristic of strong anti-interference ability to the current from industrial sources, light equipment and quick result, Hence it attracts much attention from geophysical cxploration geologists.It is specially useful in carrying geophysical exploration in the city areas It is worth dissemination.
