摘　　要：采用百度试验法研究26年生大花序桉木材的干燥特性。结果表明:大花序桉木材初期开裂严重,缺陷等级达4级;截面变形程度2级;内部开裂程度中等,为2级;干燥速度较慢,为5级。根据木材干燥特性结果,参照百度试验缺陷等级以及干燥缺陷对应的干燥条件,制定了26年生大花序桉木材干燥基准。Drying characteristics of 26-year-old Eucalyptus cloezianawood were examined using the 100 oC test method. Results showed that in wood of E. cloeziana： initial checks were serious and categorized as Grade 4; the degree of cross-section deformation was moderate and categorized as Grade 2; internal checks were also moderate and categorized as Grade 2; drying was slow and categorized as Grade 1. Based on the results obtained on the wood drying characteristics, a drying schedule for E. cloezianajuvenile wood wasproposed based drying conditions necessary to minimize drying defects.
