摘要
１６个杉木样本的木材力学试验结果表明，除横纹抗压强度外，弦面的抗弯强度和弹性模量、冲击韧性、顺纹抗剪强度及抗劈力均不同程度高于径面。分析了引起差异的原因。
The results of wood mechanical tests of Chinese fir (Cunninghamia lancelata (Lam. ) Hook) belonging to 16 sampls show that in static bending, toughness, shear parallel to the grain and cleavage wood is more resistent to a force acting on its tangential sections than on its radial sections to a different extent except compressive force perpendicular to the grain. The cause of the difference induced is analysed.
