On the basis of computer vision and finite element method (FEM) simulation technology, we build a set of measurement system of 2D RE, which provides a rapid, wide-range, maneuverable measurement method compared to the traditional coord.

However,two-dimensional inversion of EH-4 data has a problem.

Considering the influence of the topography, the authors analyzed in detail the geoelectric section model and made CSAMT two-dimensional inversion for the direct calculation data of the model.

: In order to enhance the capacity of data inversion in the electrical method and to find out a better inversion method, we have introduced and developed the Box-Kanemasu method successfully in this paper in addition to studying the application of the modified damping least-square method in a two-dimensional inversion.

The 2 D inversion is the best method in the interpretation of DC resistivity sounding profiles data owing to its high speed, but the 3 D inversion, by contrast, needs more measured data and more computer time.

After 3D forward modeling and 2D inversion,we realized the relationship between the inversion data and the real object,then we inversed the field data and given a reasonable conclusion.

At present,the researches on 2D inversion of IP data mainly aim at the HD(high density) IP data,which is mainly due to the equivalent distances between neighboring poles during data collection.

The 2D inversion cross-sections show that the eastern and western boundaries of the Songliao basin are steeper while the southern boundary is gentler and that low-resistivity objects are commonly present at 15-30 km depth in volcanic areas, which offers a basis for int.

From the approximate reduction to the inverse objective function of two dimensional layer model, the two dimensional inversion along the total profile was reduced to the one dimensional inversion of each site along the profile, and a simple easy scheme of the parametric inversion for tw.

Joint 2-D inversion of magnetotelluric sounding data having landform effect;

This paper studied the 2-D inversion interpreting technique of electrical sounding with the finite element method and the damped least square method.

A new fast magnatotelluric 2-D inversion method has been developed, which utilizing the same method as that of rapid relax inversion (RRI) to calculate the partial derivatives of apparent resistivity with respect to model parameter and presented the model structure of Catherine de Groot-Hed-lin and Steven Constable.
