| 摘 要： | 本文阐述了马尾松在浮压真空条件下的干燥特性．实验结果显示，浮压干燥比常压干燥能明显加快木材内水分迁移的速率，特别是在低含水率阶段（纤维饱和点以下）更明显．文中还对浮压条件下细胞壁内吸着水的迁移机理进行了初步的探讨分析．

| Abstract: | The paper introduces drying characteristics of Masson Pine under vacuum and floating pressures. The experimental result shows that the velogty of water movement in wood is distinctly quicker under vacuum and floating pressures than that in the atmosphere. And this phenomenon is specially obvious during low moisture content of wood (under fiber-saturation point). In addition the preliminary study of mechanism of water move in cell wall of wood was done. |
