X射线密度计法测定木材水分的分布

介绍了Ｘ射线密度计法测定木材水分分布的原理，考虑到木材失水后发生干缩，引入插值法对干缩木材的Ｘ射线扫描密度谱进行了修正，以求得木材早，晚材及各点水分分布。测试结果表明，各年轮晚材区域的水分密度大于早材区域。

Determination of Water Distribution in Wood by X-Ray Densitometry

In this paper, the principle of determining the water distribution in wood was introduced Considering the wood shrinkage after dewatering(or drying), the authors introduced insertion method to revise X-ray scanning density profile of dried wood and obtained the water distribution of earlywood, late-wood, and each point The testing results indicate that the water density is higher in latewood than that in earlywood in each growth ring
