摘　　要：利用木材常温高压微爆破法对落叶松木材进行预处理,经干燥脱脂和松节油抽提实验分析了不同爆破条件下试件的平均干燥速度及松节油脱指效果。研究结果表明:微爆破处理可以明显提高落叶松的干燥速率和脱脂效果。适当的微爆破压力和爆破次数,可以使落叶松的平均干燥速率提高40%,松节油脱除率提高1倍。A micro-explosion under room temperature and high air pressure was pretreated to Larch wood. The average drying rate and turpentine content of the skimmed test specimen under different conditions were analyzed after drying and extraction of turpentine experiments. It is indicated that the micro-explosion treatment had a obvious improvement to the drying rate and the degreasing effect for Larch. Appropriate air pressure and number of explosion could increase the drying rate of 40% and the degreasing effect of 100%.
