Development of software based on near-field measurement of airgun array for simulation of far-field wavelet;

Development of Haibao series shallow water airgun seismic source vessel and its application;

We applied shear wave splitting analysis to a seismic dataset generated by airguns in a reservoir.

Three aspects of the progress in the seismic wave radar research were summarized: the transplantation of air gun technique,developed over the last 20 years of the 20th century,from the Marine to the mainland,the applications of the electromagnetic wave radar theory and information technology to seismology,and the new seismic array observation technique that lately emerged.

Design and Improvement of Gating and Exhausted System in Die Casting Die for Airless Gun;

Development of software based on near-field measurement of airgun array for simulation of far-field wavelet;

Design and optimization of airgun array in transient zone of shallow sea;

The paper introduced in detail the development and application of airgun source and made summary of airgun theory and technology mainly from three aspects: developing history of airgun system,theory of airgun and relevant knowledge,and study of airgun array wavelet and developed results of correspondent software.

Mathematical modeling and simulation of pneumatic nail gun;

Three dimensional compressible numerical simulation is studied for the charging process of outer cylinder in pneumatic nail gun by using the κ-ε turbulence model,and the design parameters of damping hole are also discussed.
