Integrated analysis of 7 times heavy rain in Yunnan from July 19 to August 2 based on actual observation weather datum and satellite cloud atlas and Doppler radar image. The results show that: high-low southwest jet stream is important effect system. The maintenance of southwest jet stream provides water vapor, momentum, fast transfer of unstable energy for the lasting heavy rain. The further configuration of plateau shear line and southwest jet stream is necessarily condition about 7 times heavy rain. The lasting heavy rain appeared on big value region of 500hPa vapour flux and vapour flux divergence. The shear cloud band and subtropical high cloud band crossed and confluenced in Yunnan on the satellite cloud atlas. The maintenance and intensification of shear cloud hand and periphery cloud band of subtropical high correspond quite well to heavy rain falling region and cloud band distribution.

In section one, by using FICE scheme and TIME-GCM, a model of trace gases and OH airglow affected by gravity wave is set up, then the propagation of nonlinear gravity wave and the effect on trace gases and OH airglow are analyzed. The result shows gravity wave excited by tropospause forcing can propagate stably to the mesosphere through the stratosphere so that energy and momentum can be transferred from one region to another. In this process, gravity wave undergoes growth, overturning, convection and breaking. And the no-isothermal structure can accelerate the breaking of gravity wave in mesospause, and the breaking of gravity wave is an important source of convection and small-scale waves.

Based on the free radical reaction kinetics, kinetic models of the free radical polymerization and grafting were constructed, and expressions of reaction rate, monomer concentration, monomer conversion and initiator concentration were deduced. According to the statistical theory of polymeric reactions, the average molecular weight can be divided in three hierarchies: the first is that of polymer chains instantaneously produced, the second is that of polymer chains considering the cumulative effect and the third is that of the fluid with both the reactant and the production taken into account. Expressions of the number-average molecular weight and weight-average molecular weight for each hierarchy were constructed. The continuity equation, the momentum equation as well as the initial and bondary conditions were derived to describe the viscous incompressible fluid flow process. On the basis of polymer physics, expressions of zero shear viscosity and apparent viscosity related to processing conditions and material structures were built.
