树木生长轮材质分析。是研究不同生态条件下木材材质变异及预测的重要技术措施。本文以湖南会同的杉木为材料,通过生长轮材质分析方法测定的小试件压力、小试件拉伸、显微硬度、生长轮密度、生长轮晚材率,与木材标准试验测定的顺纹抗压、顺纹抗拉,端面硬度,木材密度及晚材率的对比中,得到了非常接近的规律。单相关系数大部分在0.7以上.变化较大的小试件拉伸与顺纹抗拉也在0.62以上。证实了这项研究方法的可靠性。
Tree Growth Wheel Material Analysis. Is to study the different ecological conditions of wood material variation and prediction of important technical measures. In this paper, we use the same Chinese fir as the material, through the growth wheel material analysis method to determine the small sample pressure, small sample tensile, microhardness, growth wheel density, growth rate of late grain, Compressive resistance, parallel grain tensile, end hardness, wood density and latewood rate of contrast, get a very close rule. Most of the single correlation coefficients are above 0.7, while the tensile strength and tensile strength of the small specimen with larger changes are above 0.62. Confirmed the reliability of this research method.
