Fractal theory is applied to do it. The definition of curve and pore area fractal dimension is introduced. Two fractal dimensions are determined by box-counting method.

The results indicate that with the increasing of pore area, the shear strength between inorganic glass and polyurethane in laminated glass first increases rapidly, and then decreases slowly.

As the intensity of air—oxidation treatment increased, the surface area of the PSAC decreased, but its total pore volume increased.
