摘要
研究了马尾松枝桠材中的应压木和对应木的化学、物理及力学性质.并与正常干材对比。结果表明:它们在化学组分、纤维素相对结晶度、密度、胀缩性、吸水性、顺纹抗压、抗弯强度及其弹性模量等方面存在明显的差异。
The chemical. physical and mechanical properties of compression wood and opposite wood of branches from Masson pine have been determined and compared with the properties of normal stemwood in this paper.The results demonstrate that there are marked differences among three types of wood tissues in chemical composition. in degree of relative crystallinity of celluose. in density. in shrinkage and swelling, in water absorption. in compression strength parallel to grain. in static bending strength and its modulus of elasticity.
