摘要：

Capillary pressure, hydraulic conductivity and the capillary dispersion coefficient have been observed to obey power laws in the wetting phase saturation. We relate power-law behaviour at low wetting phase saturations, i.e. at high capillary pressures, to the thin-film physics of the wetting phase and the fractal character of the pore space of natural porous media.
