| 摘 要： | 为了对进一步研究纤维的超分子结构及木材的宏观特性提供基础数据,利用X射线衍射法分别测量了白桦(Betula platyphylla)、云杉(Picea koraiensis)、落叶松(Larix gmelinii)和杨树(Poplar)健康材和腐朽材的结晶度。对X射线衍射仪测量的结果进行计算得出:白桦健康和腐朽边材的结晶度分别是43.36%和31.60%;云杉健康和腐朽边材的结晶度分别是41.90%和29.04%;落叶松健康和腐朽边材的结晶度分别是53.59%和40.20%;杨树健康和腐朽边材的结晶度分别是70.26%和48.29%。结果表明,同一树种,腐朽材与健康材相比,结晶构造没有发生变化,但结晶度下降,说明腐朽破坏了纤维结晶区的结晶程度。

| Abstract: | An experiment was conducted to measure the crystallinity of the healthy and rotten wood of Betula platyphylla,Picea koraiensis,Larix gmelinii,and Populus spp. through X-ray diffraction,aimed to provide basic data for the further study of molecular structure and macroscopic features of wood. Result showed that the crystallinities of healthy wood of B. platyphylla,P. koraiensis,L. gmelinii,and Populus spp. were 43.36%,41.90%,53.59% and 70.26% respectively; and those of rotten B. platyphylla wood,P. koraiensis... |
