研究湿地松木材的主要物理力学性质,并对各指标间的关系进行了回归分析,结果表明:(1)按我国木材材质等级划分标准,可以得出湿地松木材气干密度属轻,强度指标属低。(2)强度指标与气干密度之间表现为一元线性关系,其中抗弯强度、冲击韧性显著。(3)抗弯弹性模量与抗弯强度具有密切的线性关系。
The main physical and mechanical properties of Slash pine wood were studied, and the regression analysis was made between the indexes. The results showed that: (1) According to the classification standard of wood materials in China, the dry density of Slash pine wood was light, Is low. (2) There is a linear relationship between the strength index and air-dry density, in which the flexural strength and impact toughness are significant. (3) flexural modulus and flexural strength have a close linear relationship.
