采用NR-1000温度采集系统对多张预干桉木单板热压干燥过程中水平方向和竖直方向的温度场进行了测定与分析。工艺为目前企业对多张单板热压干燥的常用工艺，即压力0．2 MPa、温度120℃、干燥时间30 min，上下热板间整齐重叠放置10张单板。结果表明：在水平方向上，整个干燥过程中单板的中心温度高于边缘温度，除与热板相近的2层单板（1、10号和2、9号）和初始阶段的3、8号单板外，其余单板水平方向的温度均存在显著差异；在竖直方向上，温度场以5、6号单板为中心呈上下对称分布，靠近热板处的单板温度高，中间单板温度低；按对称位置分成5组后，组间单板温度存在显著差异，组内单板温度差异不显著。结果可为进一步开展多张单板热压干燥机理以及干燥单板质量的研究提供基础数据。

The horizontal and vertical temperature field of multi pre-drying eucalyptus veneers during hot press drying was detec-ted and analyzed by NR-1000temperature acquisition system.The hot press dryingprocess was used in current corporate for multiveneers with 0.2 MPa of pressure, 120℃of temperature, 30 min and 10 veneers laid overlap in order between two platens.In the horizontal direction, the center temperature of veneers is higher than that in the edge temperature dur-ing drying process.Except two layers veneers near the platen (NO.1 and NO.10, NO.2 and NO.9) and NO.3, NO.8 veneers in initial stage, the horizontal temperature of all veneers has significant difference.In the vertical direction, the temperature field taking NO.5 and NO.6 veneers as center were symmetrical.The temperature of veneers near the platen is high, while that of middle veneer is low.Ten veneers were divided into five groups by symmetric position.There is a sig-nificant difference in veneer temperature of different groups, while the difference of veneer temperature in same group is not significant .
