摘　　要：以65mm红柳桉锯材为研究对象,采用4种不同的干燥基准对其进行初步探究。结果表明:干燥前期表层含水率下降速度快,芯层含水率向表层迁移的速度慢,前期温度过高,干燥速度过快,木材容易开裂。采用波动干燥基准,利用温度监控设备控制干燥过程的实施,可以有效地减少65mm红柳桉干燥过程中的开裂现象,缩短干燥周期。65mm thick Shorea spp. lumber and four different kinds of drying schedules were used to explore the lumber drying process. The results indicated that surface moisture content of the lumber decreased faster but moisture migration from core layer to surface layer was slower.The experiments showed that the lumber cracked easily when initial temperature was too high and drying rate was too fast. The fluctuant drying process with temperature monitoring device controlling the implementation of the drying process can effectively reduce 65mm thick timber cracking in Shorea spp. drying process and shorten the drying period.
