为了研究杉木苯酚液化工艺过程中液化产物动态黏弹性的变化规律，采用动态黏弹性分析（DMA）方法，在频率1、10、50Hz，温度-120～100℃条件下，测定了不同液化工艺因素制备的杉木苯酚液化产物的存储模量E’和损耗因子t驴温度谱和频率谱，讨论了液化工艺因素对杉木苯酚液化产物动态黏弹性的影响。结果表明：在测试温度范围内液化产物存在一个玻璃转化温度T8；O～50℃范围内有一个α’松弛过程，50～100℃范围内有一个α＂松弛过程，且α＂松弛过程的活化能高于a＇的活化能，α＇的活化能随着液化时间增加而增大，α＂的活化能则随着苯酚与杉木质量比的增加而减小。
In order to understand the dynamic viscoelasticity property of phenol liquefaction products from Chinese fir, this research studied storage modulus E＇ and loss factor Tgδ property at 1Hz, 10Hz, 50Hz and -120～100℃ using dynamic mechanical analysis and discussed the effect of liquefaction factors on dynamic viscoelasticity. The results show that a glass transfer temperature （Tg） occurs in the liquefaction products. An α＇ relaxation peak exists at the range of 0～50 ℃ and an art relaxation peak exists at the range of 50～100℃. The activation energy of α＂ is much higher than that of α＇. Moreover, the activation energy of α＇ increases with the increasing of liquefaction time, while the activation energy of α＂ decreases with the increasing of the mass ratio of phenol to Chinese fir.
