X射线扫描法和切片法测量干燥过程中杉木含水率分布的比较研究
Comparison of X-ray scanning and slice methods for moisture distribution measurements when drying Cunninghamia lanceolata plantation wood
摘要
Abstract
To test measurement accuracy of the X-ray scanning method and to explore its feasibility for determining moisture content distribution with Chinese fir plantation wood (Cunninghamia lanceolata),the X-ray scanning and slicing methods were compared during the conventional drying process.Results with the two methods for each drying stage showed no significant differences (P ＞0.05).In addition,a regression analysis revealed R2 ＞ 0.90 for the two methods.During the entire drying process,the moisture content of each layer measured with the slice method was lower than the X-ray scanning method; however,differences were greater when moisture content was high.Thus,using X-ray scanning to measure the moisture content distribution of wood during the drying process would be practical.关键词
