摘要：
The process of absorption of water within a cross-section of a sheet of Scots pine sapwood, and the following step of desorption, are studied, when the moisture content is beyond the fiber saturation point. A two dimensional transfer through this cross-section is considered with the two principal diffusions: longitudinal and radial. A numerical model with finite differences is able to describe the process, by calculating the kinetics of transfer as well as the profiles of moisture content developed through the wood section.
