A study based on diffusion theory for exchange-reaction of RLA model;

A study of sediment transport from the equations of turbulent two-phase flows──A discussion on diffusion theory and diffusion coefficient of sediment;

Based on the analysis of characteristics of sediment particle concentration distribution,it is pointed out that the diffusion theory can describe sediment concentration distribution in main flow region but cannot explain sediment concentration distribution law near bottom because of the existence of sediment colliding shear stress.

Seismic wave scattering theory, scattering characteristics and its applications.;

The view of seismic wave scattering theory and its applications;

In This paper,seismic attenuation mechanism based on physical rocks and scattering theory was reviewed.

Based on the dissipative structure,this paper presents that comprehensive therapy or medicinal treatment combined with social and psychological methods keeps internal envourment of the neoplasms patients in ordered homeostasis to improve the conditions of the patients by way of increasing the amount of entropy.

LIN Fei has made a significant contribution to the contemporary prose ontological research and construction in China,constructed his own entire category system of prose theory,and played a leading role in the research and development of the prose theory and the prosperity of prose creation in the new era.

This thesis combing the prose theory of Liang-han and drew some condusion.
