Abstract:Wood drying is an important link in the utilization of wood processing with a reasonable drying process being very important to ensure drying quality and to improve the wood utilization rate. To obtain the basic drying characteristics and to prepare a reasonable drying schedule for Tsoongiodendron odorum wood， drying characteristics were determined using the 100 C test method. Results showed that T. odorum wood dried easily with the cross-sectional deformation degree being light（from grades 1 to 2） and the drying speed being fast （grade 2）. However，there were serious problems with the initial checks （judged to be grade 3） and with the degree of twist deformation（grade 3） having no internal cracks and a small volumetric drying shrinkage coefficient. Considering the main drying defect level and the defect level of the 100C test method as well as the drying conditions corresponding to the drying defects，a reference drying schedule for T. odorum wood with a thickness of 25-30 mm was drawn up to provide a theoretical basis for control in a practical，kiln-dried process. ［Ch，1 fig. 2 tab. 13 ref.］
