摘要：Taken the eucalyptus pellita treated for example, this article introduced the microstructure of wood without heat-treatment and microstructure-change under different temperatures (80°C, 120°C, 160°C, 200°C, 240°C, 280°C), analyzed the affect of the thermal treatment on wood's physical-mechanical characteristic from microstructure. The result shows that: 1) pit membrane on the vessel tended to be broken or deciduous; 2) as the temperature ascending, fiber appears wizened and some grows rose, cell cavity trails off, severing of fiber could be saw on the transverse section, and brittle fracture on the radial cut; 3) weight reduced as temperature went up, while bending strength and modulus of elasticity descending after ascending, vertex appears when the temperature was 120°C, resistance was seriously lost at 280°C. ?
