对１５株浙江产杉木株内不同高度和圆周不同方位上木材的抗弯强度、抗弯弹性模量、顺纹抗压强度和木材密度的差异，木材密度的径向变异模式和木材力学性质与木材密度的相关关系进行了测定和分析。主要结果是：抗弯强度和抗弯弹性模量在株内不同高度上差异特别显著；顺纹抗压强度和木材密度未表现出显著差异；在圆周不同方位上，三项力学性质和木材密度均为南北向高于东西向，差异不显著；木材密度径向变异模式在不同高度和不同方位上均为接近水平有一定波动的直线；三项力学性质与木材密度的相关关系在不同高度和不同方位上均特别显著，但不同力学性质与木材密度的相关系数有明显差异，不同高度上和圆周不同方位上，亦有差异。
The difference of flexural strength, flexural modulus, compressive strength of parallel grain and density of wood, radial variation of wood density and mechanical properties of wood in 15 different strains of Zhejiang fir The correlation of wood density was measured and analyzed. The main results are as follows: the flexural strength and flexural modulus at different heights in the plant are significantly different; compressive strength of parallel grain and wood density showed no significant difference; in different azimuthal directions, the three mechanical properties and wood density And the difference was not significant. The radial variation pattern of wood density at all different heights and azimuths was a straight line with some fluctuations near the horizontal. The correlation between the three mechanical properties and the wood density at different heights Especially in different directions. However, the correlation coefficients between different mechanical properties and wood density are obviously different. There are also differences at different heights and in different azimuths of the circumference.
