Our main work is as follows: the stable laser mode theory in uniform plasmas is extended to non-uniform plasma cases; the discussion of the sufficient and necessary conditions for laser self-focusing in uniform plasmas is developed to non-uniform plasma cases; a quantitative approach to judge the impact of different plasma density distribution on laser self-focusing is proposed; the evolution properties of asymmetric laser filed in non-uniform and uniform plasmas are discussed and mechanisms that symmetric channel-like plasmas can confine the laser centroid around the plasma channel axes and symmetrize initially asymmetric laser beams are proposed; the formation of solitary standing wave in moderate plasma density is studied by PIC simulations and can be explained by stimulated Raman scattering of laser beams in plasmas.

In order to clearly recognize the geophysical response of carbonate reservoir,based on preliminary recognition of Ordovician carbonate reservoir under the basal surface in Tahe oilfield,some regular vug models and random arranged vug models were designed and built. The variable-grid finite difference method was used to simulate the seismic wave propagation in these models. Then,the seismic records of the models were analyzed and the effect to seismic reflections caused by vug is studied. The impact rule of regular vug scale and random arranged vug density on seismic attributes was obtained.
