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

The methane-coalbed coupling movement theory researches the mutual action law among the framework deformation of porous media, the adsorptive deformation of grain, the diffusion-desorption of adsorbed fluid, and free fluid seepage, so that scientific basis is provided for the decision to exploit methane, prevent and co.

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.
