本文借助通径系数分析及主成分分析等统计方法,以五株产自山西中条山的辽东栎为试验材料,详细研究了木材解剖特征的内在关系以及解剖特征与物理—力学性质的关系。结果表明,“细胞特征”(纤维、导管尺寸及微纤丝角等)和“组织比量”(导管、纤维及薄壁组织比量)两个主因子基本反映并代表了木材的所有解剖特征,同时也是影响木材物理—力学性质的两个基本解剖因子。
Based on the statistical analysis of path coefficient and principal component analysis, five Q. liaotungensis produced in Zhongtiaoshan of Shanxi Province were used to study the relationship between the anatomical characteristics of wood and the physical-mechanical properties. The results showed that the two main factors of “cell characteristics” (fiber, catheter size and microfibril angle, etc.) and “tissue ratio” (catheters, fibers and parenchyma ratios) basically reflected and represented all anatomical features of wood , But also the two basic anatomic factors that affect the physical-mechanical properties of wood.
