in order to improve converted-wave DMO ,we advance a new P-SV wave DMOmethod in frequency wavenumber domain which is based on inclination decomposi-tion.
As the advance of seismic exploration, the precision of the geophones is improved incessantly; the way of the data gathered is updated constantly, the density of the geophones in a prospected region is much increased.
This thesis tries to act from two aspects: applies object-oriented programming method to advance the development and maintenance efficiencies of programs;
applies finite elements coupled with infinite elements to reduce the computational domain of geotechnical engineering so as to advance the calculation efficiency of programs, and service to the numerical simulation of the post-failure mechanical properties of brittle-plastic rocks finally.
Author suggests that a new cross-subject between geodesy and present-day geodynamics, system dynamic of intraplate crustal deformation, should he developed at once in order to advance intraplate earthquake predication and study of seismogenic procces to a new level.
Experiment data also show that surge irrigation have many advantages, such as fast advance, high uniformity and high irrigation efficiency, than continuous irrigation.
Production log data can moni-tor oil field production performance and bottom water advance, and is the foundation ofwater blocking scheme in a high water bearing reservoirs.
In particular, when the new shape parameter of the distribution under progressive stress is given (or estimated in advance), the closed forms of these estimators are relatively simple and are numerically accessible on computers.
