The feasibility and effectiveness of the non-uniform initial model by approximate inversion method to 2D inversion are verified through inverting the simulated and measured vertical electrical sounding data.

Based on the published paper of present anthor (Ruan & Xu,1996) and Siegel s model of polarizability,this paper first derives a direct inversion method for interpretation of IP sounding curves.

Based on the Dar Zarrouk curves and the conception of longitudinal conductance and transverse resistance,a direct inversion method of one-dimension direct current sounding curves is derived.

The BP neural network is introduced in direct inversion with measured data of flow as input value and river roughness as output value.

A retrieval method of antenna pointing information of “SZ-4” space-borne altimeter;

A new retrieval method for deducing path-integrated cloud liquid water content(LWC) by airborne upward-looking microwave radiometer is introduced in this paper.

The retrieval methods of lidar-determined aerosol optical propert.

Studying on Inversion Method and Application of Logging While Drilling Response;

Different inversion software bases on different inversion method, so the application conditions and results are varying.

Based on the simulated data produced by PROSAIL model and field test data, the authors respectively analyzed many kinds of factors which affect some representative inversion methods, such as VI, second derivative, model inversion and the directional second derivative.
