基本容重γy(条件容积重),就是全干材重量和生材体积之比.它为一般材性的依据,在含水率相同的情况下,容积重是决定木材强度最主要的因子,苏联学者M.别列雷金的意见:不论什么树种,容积重都是判断木材物理力学性质最可靠的特征。我国尹恩慈、谢福惠等先生也论述了容积重和木材力学性质的关系,在各树种及同一树种的不同植株之间,均有同一趋向,即容积重大,强度亦大,这种关系可以用曲线或直线方程来表示。现就用我们所测的25个树种木材的资料,试进行木材力学性质与基本容重关系的数学模拟研究。
The basic bulk density γy (conditional volume weight), is the ratio of the total dry wood weight and raw material volume.It is the basis for the general material, with the same moisture content, volumetric weight is the most important factor in determining wood strength, Soviet scholars M. Bererekin’s Opinion: Regardless of species, volumetric weight is the most reliable feature in judging the physical-mechanical properties of wood. Yoon Enci and Xie Fuhui in China also discussed the relationship between volumetric weight and mechanical properties of wood. There is a common tendency among all tree species and different plants of the same tree species, ie large volume and high intensity, and the relationship can be expressed as a curve Or linear equation to represent. Now we use the measured 25 species of wood materials, test the mechanical properties of wood and the relationship between the basic mathematical simulation study.
