摘要
根据断层扫描基本原理导出用断层扫描技术检测木材含水率的新方法。用杉木试件实验验证的结果表明,木材含水率与木材断层扫描值存在高度线性相关,相关系数在0.9以上。该方法在木材含水率在纤维饱和点以上和以下都适用。
In this paper, based on X-ray computed tomography, the author describes a new method of moisture content measuring in wood. Cedar samples were tested to verify the accuracy of this new technique. From the experiments an excellent linear relation between moisture content in wood and X-ray commutated tomography number, which is as high as 0.9, can be applied when the moisture content both above and under the fiber saturation point.
