| 摘 要： | 本文通过木材自由水在相变过程中的介电弛豫现象,就木材中水分的存在机构、冻结自由水的介电弛豫同吸附水的相似性、以及木材吸附水的介电弛豫机构和冰的类似性作了一些讨论。并且提出了一种利用木材中水分的介电特性量随温度的变化关系来确定木材纤维饱和点的方法。

| Abstract: | The changes of the dielectric properties of free water in wood during phase transition were investigated. In the light of the results, the existing state of the water in wood, the analogy of dielectric relaxation between the free water under freezing and absorbed water and the analogy of dielectric relaxation between absorbed water and ice were discussed in this paper. By considering the relationship of the dielectric characteristic parameter resect to temperature, the method to determine the moisture content in fiber saturation point was proposed. |
