摘　　要：在大气湿度循环变化的过程中,木材含水率随之改变,导致木材胀缩性发生变化,引起家具零部件松动,甚至脱落和开裂。采用人工模拟大气湿度变化规律,对尾巨桉木材进行循环干湿处理,探索尾巨桉木材含水率的变化规律,旨在探索降低尾巨桉木材胀缩性的新途径,为尾巨桉木材干燥和实木加工提供新理论。The wood would have movement with its moisture content when the humidity content of air loop changed. And furniture parts could loose and pull out. Eucalyptus urograndis wood was loop dried and absorbed according to simulating humidity content of air. The dried wood was tested and measttred by FHR in order to disclose that Eucalyptus urograndis wood moisture content should have the model and mechanism of change and to lower its wood movement.
