| Abstract: | Based on commonly used PC system, image processing software ImageJ and stereology theory were applied to develop a new method of measuring and calculating pore structure parameters including porosity and pore size from porous materials such as coal char. Other parameters as circularity and coarseness that may relate to physical property of coal char like strength were also calculated according to stereology, which may be helpful for the study of physical property of porous materials theoretically. The advantages of this method are low demanding for the equipment, and strong objectivity and high efficiency for analyzing and calculating operation. |
