摘　　要：利用相关分析方法,对中国主要树种木材物理力学性质之间的关系进行了综合分析。结果表明,木材的物理力学性质之间,除个别项目外,均存在着很高的相关性,其相关关系可用直线或曲线回归方程表示;密度与冲击韧性及硬度宜用曲线回归方程表示;除硬度之外,径弦向(面)之间的力学性质都有显著差异;对于一些相互关系密切的项目,可用相关比值加以分析。The physical and mechnical properties of main wood species in China are analysed synthetically using the method of correlation analysis in this paper. The results show that the relevance are very high between the physical and mechnical properties of wood except a few items. The relation can be expressed by linear or curviliaear regression equation. The relations among the density and the toughness and hardness can be showed by curvilinear regression equatton. The mechnical properties between radial section and tangential section are remakably different except hardness. We can analyse the relationship of some items by the ratio of correlation.
