摘　　要：以日本柳杉（Cryptomeria japonicaD.Don）为试材,经温度为140,160,180℃,相对湿度均为100%的过热蒸汽处理及干燥后制成木地板,对其吸湿解吸特性及化学成分进行分析,考查在潮湿或干燥的自然环境使用中的尺寸稳定性.研究结果表明：经高温过热蒸汽干燥处理后的木地板尺寸稳定性得到了改善.Japanese Sugi（Cryptomeria japonica D.Don）wood was dried by superheated steam under the temperature of 140,160,180℃ and the relative humidity of 100% to make wood flooring.Moisture absorption and desorption characteristics and chemical composition of treated wood were analyzed to investigate the dimensional stability at saturated and dry ambient condition.The results showed that the dimensional stability of wood treated with superheated steam under high temperature was significantly improved.
