本文以人工林杉木(Cunninghamia lanceolata)为研究对象,采用X射线扫描法分析常规干燥过程中干燥介质相对湿度恒定时(40%),干燥介质温度(45、55、65、75、85℃)对干燥速率的影响。结果表明:1)常规干燥中,FSP以上时随着干燥介质温度的升高,木材各层的干燥速率逐渐增大;2)FSP以下时木材各层的干燥速率及整个干燥过程中各层干燥速率呈现与含水率梯度类似的"内高外低"曲线

　　Taking Chinese fir plantation wood(Cunninghamia lanceolata) as experimental material,the X-ray scanning method was used to analyze the influence of temperature on drying rate of wood in drying kiln where the relative humidity was kept constant at 40%with various of temperature(45,55,65,75,85℃).The results shown that:1)During the conventional drying process,with the increase of the temperature,the drying rate of each layer increased gradually;2) The drying rate gradient occurred that the internal layer had a higher drying rate than that of ...
