Conversion points of converted wave in vertical inhomogeneous media;

A unique solution with traveltime for the P-SV wave conversion point in a horizontal reflector;

The propagation path of P-SV converted wave is non-symmetric,but the stack of converted wave requires real common conversion point gathering.

Seeking for the non-disciplinarian breaking point on double-declining balance method;

Harmonic distortion exists in sinusoidal wave generated by digital synthesis technique with its value is related to not only the number of converting points in a period but also the word length of the D/A converter.

An analysis is presented, by use of the Fourlier Series, of the mathematical relations of THD with the total number of converting points in a cycle of sine function, phase shift resolution and the number of sampling points.

Calculation procedures for common conversion points of PS converted waves and their application;

A method for fast and accurately computing the common conversion point locus.;

According to the real data,the process-interpretation method of multi-wave and multi-component seismic data is discussed and studied in this paper,mainly aiming at the static correction and stack imaging of multi-wave data,as well as the computing method of common conversion point of converted wave etc.
