通过对３ 种阔叶树 （米槠、木荷、拟赤杨） 枝桠材的应拉木和对应木的解剖特征及材性的观察和试验，并与正常干材比较， 结果表明： 它们在纤维、导管的长度、宽度、纤维次生壁 Ｓ２ 层纤丝角、化学成分、纤维素相对结晶度、密度、吸水性、涨缩性以及顺纹抗压强度、抗弯强度及其弹性模量等都存在显著差异。 Through the observation and experiment of the anatomical characteristics and the material properties of the branches and leaves of three broad-leaved tree species (Miriam, Schima superba, Alnus mirabilis), and comparison with the normal dry materials, the results showed that: The length and width of the tube, the S2 filament angle, the chemical composition, the relative crystallinity, the density, the water absorbency, the shrinkage and the compressive strength, the flexural strength and the elastic modulus There are significant differences.
