摘要：

Image analysis has been applied to the TEM observation of activated carbon fibers, in order to evaluate the pore structure visually. It is suggested that the present method can show the shape of the pores as well as providing a quantitative estimation of the pore structure. The results are consistent with those obtained by common gas adsorption method and with synthesized molecular graphics TEM images of pores. The pore analysis on activated carbon fibers by TEM combined with image processing can provide a powerful tool to characterize the porous structure of activated carbons from a different new viewpoint.
