查询词典 continuous wave

Though in the impact process exists rebound phenomenon and the wave form becomes interrupting impulses, yett the energy loss of the mass is very low. So it is thought to link the interrupting impulses to a continuous wave form by using proper way and then to process the data by mature vibration analyzis technique.

Based on wave propagation feature, this paper analyses 3D seismic migration algorithms such as alternating direction implicit method, LU decomposition method, and inverse operator approach method. The result shows that the alternating direction implicit method is fast but causes distortion in wave field extrapolation and affects image accuracy; however LU decomposition and inverse operator approach methods are fast while holding circular symmetry of wave field, and are promising in oilfield exploration and development.
