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.

PartⅡ,Applying the developed and extended direct algebraic methods that presented in recent years and based on the 2+1 dimensional variable separation solutions,abundant Jacobi elliptic function doubly periodic waves and periodic propagating wave patterns for many 2+1 dimensional nonlinear wave models are obtained,and in long wave limit solitary waves are derived as well.

In Chapter Two, some methods such as electron microscope, DNA ending label and MTT measurement were used to studied the changes of apoptosis, necroses and cell vigour of leukaemia K562 cell trunk and HL-60 cell trunk irradiated with millimeter wave. Different effects of millimeter wave to leukaemia cell trunks and human marrow cells were observed clearly. Human marrow cells were not so sensitive to millimeter wave radiation as leukaemia cells.

In this paper an algorithm of finite element modelling is discussed for elastic wave propagating in two dimensional media. Two analytical formulas of the initial motion and wave form of P wave are derived in time domain for a point force source directing vertically down as a function of time with a bell shape.

Some one disagree our viewpoint, so at last we clarified that why this term vanishes identically when one rigorously studies the intrinsic magnetic moment of a particle, either fundamental or composite even we have chosen wave packets instead of plane wave, i.e. a superposition of physical plane-wave states, because they are strictly physical and practical.
