两种木材的力学性质与气干密度表现为显著的正相关关系。
There was a remarkable positive correlation between mechanical properties and air-dried density for two wood species.
种源内木材气干密度、力学强度及胞壁率差异不显著,管胞长、宽和壁厚的差异均显著且高于种源间的差异。
Meanwhile, there were not significant differences in wood air dry density, mechanical strength and cell wall percentage of intra provenance.
在物理力学性质指标中成熟材的基本密度、气干密度、顺纹抗压强度、抗弯强度、抗弯弹性模量及冲击韧性高于幼龄材;
In physical and mechanical indexes, the basic density, air-dried density, compression strength parallel to grain, MOR, MOE and toughness of mature wood are higher than that of juvenile wood.
用X射线扫描密度计测量气干材含水率及其每一年轮的水分分布。
In this paper, the moisture content and its distribution of each growth ring in air dried wood specimens have been tested by using X-ray scanning densitometer.
