| Abstract: | By means of the high-density micro-electrical measurement system,the numerical simulation forward modeling and smooth-constrained least-squares method inversion,this paper analysed the way to obtain the abnormal body interface under the border-effect and studies the statistical relation between the resistivity value of the border and the resistivity values on both sides of the border that can be read on the inverse geoelectric section.The results show that there is a transition zone on the inverse geoelectr... |
