【Abstract】 The mechanisms of paper-scanning and image reconstruction with CT scanner were introduced briefly in the article,and the CT-scanning technique was used for analysis in inner structure of paper sheet,including the variation of porosity,size,number and distribution of the porosity in Z-direction of paper sheet.Results indicate that CT scanner is an efficient mean in inner structure analysis of paper sheet.更多还原
