| 摘 要： | 以自然生长的带有树瘤的旱柳为研究对象,对瘤材和正常材的解剖特征和物理性质进行对比研究。结果表明:瘤材的纤维宽度、纤维壁厚、纤维的壁腔比等指标均有增加,纤维的长度、纤维长宽比、导管长度、导管宽度、导管长宽比等有所减小;密度、顺纹干缩率增加,径向干缩率和弦向干缩率减小;差异干缩量减小,接近于1;水容量也有所降低。

| Abstract: | Inthis paper,Salix matsudana with natural burl woods was picked up as the trial material, and the anatomical characteristics and the physical properties of the burl woods were studied and compared with the mormal woods.The result shows that compared with the normal ones,the fiber width,fiber wall thickness,fiber wall-width ratio all reduced;and the density and longitudinal shrinkage increased in the hurl woods.The ratio of tangential to radical shrinkages in the burl wood trended towqrds 1.Based on this research,the theoretical conferences could be provided for the machining and utilization of the burl woods. |
