摘　　要：采用扫描电子显微镜(SEM)对纸张的Z向结构进行了观测,进一步对所得的观测图片应用Image-Proplus5.0图像分析软件进行了计算机量化分析。以上计算机图像分析技术利用纤维、孔隙以及纸张所含的填料在扫描图片中的颜色深度差异,通过彩色分割和填充原理对纤维、孔隙和填料的分布特性分别进行分析检测。通过该图像分析技术,可以准确测量出分布在纸张Z向不同深度上纤维以及细小纤维的长度、宽度和面积,可以准确检测出在纸张Z向各层的孔隙尺寸、孔隙分布规律、孔隙数量和所占面积比率。The Z-direction structure of paper was observed with scanning electronic microscopy （SEM）, then the scanned images were processed quantitatively with Image-Pro plus 5.0. According to the different color depth of fibers, pores and filler contained in the scanned image, the com-puter image analysis technique could analyze the distribution characteris-tics of fibers, pores and filler in the light of principle of segmentation and padding. The image analysis technique can accurately measure the length, width and area of the fibers and fines distributed in different depths cross the Z-direction of paper sheets. In addition, the technique can accurately detect the pore size, pore distribution, pore amount and area ratio in dif-ferent layers cross Z-direction of paper.
