摘要

利用木材中的非稳态扩散原理及其近似计算公式预测板材的含水率 ,方法是先测出该种板材的小试件在干燥过程中的含水率 ,计算出平均扩散系数 ,再利用该扩散系数计算出板材在干燥过程中各个相应时间内的含水率

Abstract

Moisture content ( MC ) is predicted by unsteady state diffusion principle of water in wood and its approximate calculation equations. The method is that first, the MC of small samples of the species is measured during drying and diffusion coefficient is calculated, then the MC of each periods during drying can be calculated with diffusion coefficient.
