摘要
用Ｘ射线扫描密度计测量气干材含水率及其每一年轮的水分分布。并与干燥法进行对比，其含水率测量误差在２％左右。
In this paper,the moisture content and its distribution of each growth ring in air dried wood specimens have been tested by using X-ray scanning densitometer. The results are compared with the data obtained from the matched specimens with a drying method.The testing errors are about 2%.The principle and the main factors which affect the testing of moisture are discussed in detail.
