The influence of hydroger bonding on solubility and diffusivity is investigated both theoretically and experimentally.

Microstructure and phase composition of the diffusion dissolution layer were determined, and the elements profile across the interface were detected, the microhardness and corrosion resistance of the surface were evaluated, and the effect of the electric field on the bonding was discussed.

Prediction method of water resources based on the information diffusion principle and BP neural network;

Self-organization algorithm for information diffusion based on epidemic theory;

The evaluation of loess slope stability based on combination of information diffusion theory and BP neural metwork;

We use information diffuse theory to evaluate dangerous chemicals transportation accident rate,and analyze the result of dangerous chemicals transportation accident with GIS simulation technology.

Aim at the overdiffuse and subdiffuse of information diffuse estimation,a multi-subject integrated optimization was given to determine diffused window width based on analyzing closest window width means and optimal window width means.

In order to improve the speed,accuracy and operability,the method of risk analysis based on information diffuse theory and the method of frequency analysis based on real coding based on accelerating genetic algorithm by which parameters of PersonⅢ curve were estimated were tried to be used to analyze the inundation loss frequency was analyzed.
