| 摘 要： | 应压木是针叶树木中一部分非正常组织,它的性质及超微结构与正常材有很大差异。应压木的存在对加工、制浆等木材利用均不利。多年来木材工作者对它进行了多方面研究。对于应压木中纤维素结晶度的分布已有明确结论,但详尽的测量和理论分析不足。

| Abstract: | The relative crystallinities in three regions (compression. transition and opposition region) of compression wood of Masson pine (Pinus massoniana) have been determined with the method of X-ray diffraction analysis, and the results of the measurement have been analysed with the theory of thermodynamics; The study showed that the crystallinity distribution in different zones of compression wood follows certain regularities which are caused by the following factors; (1) intrinsic growth mechanism of trees, (2) enviromental temperature of growth, (3) compression and tension state of trees. |
