越南香枝木解剖构造及物理力学性能研究

Anatomy structure and physical and mechanical properties of Dalbergia tonkinensis

确定了越南香枝木中文名为越南黄檀。对越南香枝木的构造特征进行解剖研究,并测试了越南香枝木主要的物理力学性能。结果表明,越南香枝木密度大,干缩率中等,抗弯强度、抗弯弹性模量高、端面硬度高。此外,比较了越南香枝木与海南香枝木的构造特征,结果显示两者之间管孔、木射线与轴向薄壁组织差异较为明显,可以作为鉴别依据。

In this paper, Vietnamese Scentedrose wood was identified as Dalbergia tonkinensis Prain. The fi- ber form and anatomy characteristics of D. tonkinensis were studied, and the physical ~aad mechanical properties of D. tonkinensis were tested. The results show that Vietnamese Scentedrose wood have high density, middle shrinkage and high mechanical properties. In addition, the anatomy characteristics ofD. tonkinensis and D. odor- ifera were compared, and the result shows that the pore, the wood rays and the axial parenchyma can be used for feature identification.
