| 摘 要： | 为寻找一种能较为科学、方便地反映木材降解程度的指标,共收集不同地方出土的13种木材,8个树种,对这些树种的考古木材与新鲜木材的含水率、干缩性、基本密度、气干密度、综纤维素等指标进行对比分析。实验表明,基本密度和最大含水率(饱水含水率)基本上能够反映古木的降解程度,可以作为反映古木降解程度的物理评价指标。

| Abstract: | In order to find a scientific way to evaluate the degradation of archaeological wood, 13 kinds of woods, of 8 species, were collected as study objects, and a comparative study between archaeological woods and new ones was conducted, including their indexes of moisture content, shrinkage, basic density, air - dried density and holocel-lulose. The results showed that the basic density and the maximum moisture content of wood can be used as the physical indexes of the degradation of archaeological wood. |
