为了改善杉木木材表层质软、强度低、耐磨性差等力学性能及其视觉特性，通过在不同温度和压力条件下，对绝干、气干、纤维饱和点和饱水状态的杉木表层染料水溶液渗透规律，应力－应变曲线，以及杉木细胞形态变形的电镜观察，确定了杉木表层软化处理工艺中染料水溶液渗透的最适条件，探讨了不同含水率状态下杉木表层径向压缩特性。结果表明：１）温度９０℃，常压－减压交替循环，试材含水率在气干与纤维饱和点之间时，是染料水溶液渗透的最适条件；２）径向压缩大变形区域Ⅱ是杉木早材部分变形的堆积；３）与２０℃，９０℃饱水状态杉木试材相反，气干状态试材在卸载时不发生瞬间变形恢复现象。
In order to improve the softness, low strength and poor wear resistance of Fir wood, the mechanical properties and visual characteristics of Chinese fir wood were studied under different temperature and pressure conditions. The infiltration law, the stress-strain curve and the morphological changes of Chinese fir cells were observed under electron microscope. The optimal conditions for infiltrating the aqueous dye solution were determined, and the radial compression characteristics of Chinese fir surface under different water contents were also discussed. The results show that: 1) the optimum conditions for the infiltration of dye aqueous solution when the temperature is 90 ℃, atmospheric pressure - depressurization alternating cycle, moisture content of sample is between air dry and fiber saturation point; 2) Is the accumulation of some deformation of fir earlywood; 3) Contrary to the 20 ℃, 90 ℃ saturated Chinese fir specimen, the sample of air-dried state does not undergo instantaneous deformation recovery when it is unloaded.
