【摘要】 将竹炭横切面与纵切面的扫描电镜照片放入计算机进行处理,得到竹炭两个切面的轮廓图像和二值化图像。运用Autocad软件,观察到竹炭孔隙形状极不规则,为曲线型,孔隙表面为非平滑表面。依据分形理论,竹炭孔隙非平滑表面具有分形特征,以盒计数法测定竹炭孔隙表面分形维数D=2.2723。对竹炭两切面的二值化图像进行像素扫描,计算出竹炭横切面孔隙率为56.26%,纵切面孔隙率为62.37%。以直观图像为研究对象,得到竹炭孔隙的基本特征,对表征孔隙结构有一定参考价值。更多还原

【Abstract】 The SEM pictures of bamboo charcoal transverse and vertical section were processed by computer to form profile and binary image.Using AutoCAD software,the irregular pore shape and curved and non-smooth surface of bamboo charcoal were observed.According to fractal theory,non-smooth pore surface of bamboo charcoal should have fractal characteristics,and the fractal dimension of pore surface was D=1.2723 in terms of the box counting method.The results of pixel scanning to two-section binary image of bamboo charcoal showed that the transverse and vertical section porosity were 56.26% and 62.37% respectively.This may provide some references for the understanding of pore structure of bamboo charcoal.更多还原
