从理论上探讨了木材胀缩的各向异性机理。采用多层木纤维模型，对Barber和Meylan（1964）提出的膨胀基体假设进行了重新表述，导出了描述木材纤维膨胀和收缩动力学行为的公式。对于建模，水分含量的变化被视为一个明确的参数。该模型有望对木材的各向异性胀缩过程进行动态定量预测，并为进一步阐明水分与细胞壁组分之间的相互作用奠定基础。一些具体的计算将在下面的报告中演示，并将结果与实验结果进行比较。
The anisotropic mechanism of wood swelling and shrinkage was investigated theoretically. The reinforced-matrix hypothesis offered by Barber and Meylan (1964) was reformulated by using a multi-layered wood fiber model, and the formula describing the dynamical behavior of swelling and shrinking wood fiber was derived. For modelling, the moisture content changes were taken into consideration as an explicit parameter. It is expected to predict the anisotropic swelling and shrinking process of wood dynamically and quantitatively, as well as to initiate elucidating the interaction between the moisture and cell wall components on the basis of the present model. Some concrete calculations will be demonstrated in the following report, and the results will be compared with the experimental ones.
