摘要
利用断层扫描技术结合木材干燥过程的特点,获取了木材干燥过程纤维饱和点以上自由水的分布状况,以及干燥过程中水分的变化图像。从图像中可以看出木材干燥过程中纤维饱和点以上水分分部是不均匀的,在干燥过程中变化也是不均匀的,这种不均匀的变化与木材结构、水分分布梯度有着密切的关系。
Obtaining the information of free water distribution above fiber saturation point and the image of moisture changing by using the technology of the wood computed tomography cominbing the feature of wood drying process. From the image, the unevenness of both the moisture content distribution above the fibre saturation point and the changing process in the wood drying process can been seen. This uneven change has a close relation with the wood structure and the moisture content grade.
