摘要：

m s−2 depending on the surface treatment. These diffusivities were however, not suitable to predict the moisture content profiles in the coated wood, which showed a strong increase close to the surface. The most accurate prediction of the moisture content profile was based on the changing surface concentration and the diffusion coefficient from sorption data of uncoated wood. In general, diffusion seemed to be the most important factor in the transport of water. Capillary flow of water only influenced the sorption very close to the surface of the wood. This aspect became more important for uncoated wood.
