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.［Ch，1 fig. 1 tab. 13 ref.］
