缅甸五种木材构造的定量特征鉴定

IDENTIFICATION OF QUANTITATIVE CHARACTERIZATION ON WOOD STRUCTURE OF FIVE BURMESE TREES

对从缅甸进口的黑酸枝、黑崖豆、缅红漆、木荚豆和榉木等五种木材,以宏观、微观、亚微观和体视显微术方法,进行了木材构造的定量特征鉴定,结果表明,这些木材比重的大小,可用木材胞壁率或木材密度指数表示:木荚豆、黑崖豆和黑酸枝具有优良的机械性能和装饰、雕刻特性;黑崖豆和黑酸校可以其木射线列数和高度的不同加以区分;缅红漆与黑崖豆和黑酸枝的主要区别在于前者有径向树胶管,后二者缺乏。最后,对这五种木材用途的适宜范围作了推荐。

By means of the methods of macroscopic structure, microscopic structure, ultra-microstructure and stereological microscopy, the quantitative characterizatian of wood structures of Dalbergia cultrata, Millettia pendula, Melanorrhoea usitata, Xylia dolabriformis and Zelkova schneideriana which were all imported from Burma has been identified. The results show that the specific gravity of wood can be expressed either by the percentage of cell wall or by the density index. Xyliadolabriformis and Dalbergia cultrata possess excellent mechanical, decorative and carving properties. The difference between D. cultrata and M. pendula can be determined by the rows and height of the rays. The main difference between M. usitata, M. pendula and D. cultrata is that the first has radia gum canals, while the latter two have not. Finally, the possible range of practical uses has been recommended.
