Abstract: Effect of temperature on drying rate and the course of wood temperature changes and internal deformation in wood during drying were inves tigated.Besults obtained are as foll cws: 1.Drying rate of Korean pine board increased as drying temperature elevated,and this effect is more significient for board of 30 mm than for board of 15 mm in thickness. 2.The typical high temperature drying process must have a period in which the core temperature of the board maintains at 100℃.In order to practise a typical high temperature drying process,the drying temperature must be above 110℃ for board of 30 mm and above 120℃ for board of 15 mm in thickness. 3.The regularities of internal deformation of wood samples dried at different temperatures were the same,but the elastic tensile deformation in the out layers reduced,while the plastic tensile deformation in the out layers and elastic tensile deformation in the internal layers both increased as drying temperature elevated.
