Application of slit island method in the measure of the fractal dimensions of pore section border in eggshells

An eggshell is porous. In this research, the ultrastructure of the eggshell was measured by using scanning electron microscopy and Image-Pro Plus software. Employing the Silt Island Method, the fractal dimensions of the pore section border were measured and calculated. It is shown that the blunt end of eggshell has larger pore structure parameters than the sharp end and the equator. The eggshell is a fractal structure and the relationship between lgA - lgL are maintained linearly. The average value of the fractal dimension of the pore section border on the sharp end, the equator and the blunt end is 1.5303.
