Fractal Nature of Wood Revealed by Drying.

摘要

Introducing the fractal theory into the study of wood and its porous properties will provide new insights. The fractal dimension of wood surface was first studied by using water-sorption. It was found that the fractal dimension was in the range of 2.5-2.8. An experiment with pressurized water absorption has confirmed the fractal nature of wood. The findings have shown that the pore space within wood could be characterized by fractal dimension or a set of fractal dimensions. But there was no explanation leading to the characterization of wood properties.
