该文首次将广义熵的概念用于分析三倍体毛白杨无性系木材密度的分布 ,同时对 7个无性系进行了方差分析 ,然后将两种统计结果进行了比较 ,说明广义熵可以用来表述木材物理量无规则变化性 .方差分析的结果表明 :各无性系在 0 0 5水平上有显著差异 ,可以挑选出木材品质较好的无性系来 .L3,L10 ,L4,L2 ,L1五个系号与对照相比 ,木材基本密度平均值均超过 5 % ,说明三倍体毛白杨的物理性质有显著优势 .木材基本密度平均值最高者为L3系号 (0 40 92 g/cm3) ,最低者为L6系号 (0 386 2 g/cm3) .广义熵概念在讨论三倍体毛白杨木材密度分布时存在着明显的规律性 ,其数值的均匀程度反映了木材密度分布的差异程度 ,这与广义熵的物理意义相符合 ,进一步可以定量的表示这种规律性 .
This paper, for the first time, uses the concept of generalized entropy to analyze the distribution of wood density in clones of Triploid Populus tomentosa and analyzes the variance of seven clones. The two statistical results are compared to show that generalized entropy can be used to describe The result of ANOVA showed that there was a significant difference in the 0 0 5 clones of all clones, and the clones with better wood quality could be selected.L3, L10, L4, L2, L1 Compared with the control, the average basic density of wood was more than 5%, indicating that the physical properties of triploid Populus tomentosa have significant advantages. The highest average density of wood L3 system number (0 40 92 g / cm3), the lowest (0 386 2 g / cm3) .Generalized entropy concept has obvious regularity in discussing the wood density distribution of Triploid Populus tomentosa and the degree of its value reflects the degree of difference of wood density distribution, which is consistent with the generalized The physical meaning of entropy is in line with each other, which can be further quantitatively expressed.
