Work Experience
From 2001 to 2002, he was a visiting scholar at the University of Utah. Now he is a researcher of Institute of Geology and Geophysics, Chinese Academy of Sciences.
Achievement
In terms of multiple wave research, since the periodicity of multiple waves is difficult to determine, an algorithm for suppressing multiple waves in the migration process is proposed. Regarding the study of reflection seismic migration process, the least square objective function migration method is proposed for the migration image blur and poor resolution, the large amount of calculation, and the lack of processing of missing data. Using the edge detection technology in image processing, a method to find faults and ancient river channels based on the least square function is proposed. For the difficulties of seismic data processing in mountainous and desert areas in western China, a 3D tomographic static correction method is proposed. The application of seismic tomography LSQR algorithm in the study of the deep structure of the earth gave a three-dimensional velocity image of mainland China (0-1100km). In the study of central China, the crustal and upper earth slowness of the north-south region of China were given. The three-dimensional velocity structure (0-200km) determines the relationship between the source distribution and velocity boundary. These achievements were published in the SCI indexed journals in the form of academic papers, with a total of 22 papers; 3 of them are the first authors of the international SCI and 6 are the first authors of the domestic SCI. At the same time, he published 1 first author paper in an important international journal. Published a scientific monograph.
