红松小拉伸强度与其各项指标的相关性 生长轮材质分析之四

Correlation between Small Tensile Strength and Some Properities in Korean Pines Analysis of Wood Quality of the Growth Ring(4)

以林木的单一生长轮,制成小薄片试件经过小拉伸试验,测定出每年不同的生长季中林木材质的变异。在进行拉伸试验的同时,又作了管胞分子长、纤丝倾角、木材密度以及生长轮宽的测定,结果是它们之间存在着相关性。

With a single growth ring of wood, small laminate specimens were made and tensite strength was tested in order to understand wood quality variations in different growth seasons. Meanwhile, tracheid length, fibril dip angle, wood density and growth ring width were measured. The resuets showed that small tensile strength is related to these properties.
