摘要
应用杨树木材横切面的细胞直径分布描述木材横切面空隙分布的分形特征。通过对不同高度处木材细胞腔直径分布进行分析,分别计算出它们的分形维数(D=1.24-1.31)。结果表明:腔径分布分形维数的大小可以作为表征木材多孔性的一个参数。
In this paper, the principle of fractal geometry was applied to describe the fractal properties of poplar wood cell lumen distribution. Wood cell lumen distribution in three heights were analyzed. The fractal dimensions were calculated. It ranged at 1. 24-1. 31. The results showed that the fractal dimension of wood cell lumen distribution could be as an important parameter to characterize the porosity of wood.
