| 摘 要： | 本文以杉木(Cunninghamia Lanceolata(Lamb.)Hook)为试材,采用生长轮材质分析和数量化理论的方法,研究了生长轮宽度、晚材率、树龄(生长轮在卡对干中的年龄)和气干密度等四因子与木材主要力学强度:顺纹抗压,顺纹抗拉,抗弯弹性横量,冲击韧性和端面硬度等六项指标的相关性,并分别获得了它们的相关方程式。

| Abstract: | With samples of Cunninghamia Lanceolata(Lamb.)Hook as testing
material,the correlation between growth factors and main mechanical
properties of wood was researched by means of the theory of quantifica-
tion and quality analysis of growth rings.The growth factors included the
width of growth rings,the rate of late wood,the ages of growth rings and
the density of air seasoned wood.The main mechanical strengths involved
compression strength parallel to grain,tensile strength parallel to grain,
bending strength,elastic modulus of static bending,toughness value
and hardness of crass section.The corretion equations between them were
obtained respectively. |
