摘要
木材表面自由基与温度间存在着显著的相关性.温度的变化导致木材表面形变产生机械自由基,同时它又影响木材中水分的输运过程.两者的联合作用构成了木材表面自由基与温度变化相关性的复杂性.本文在-196～+180℃温度范围内研究了木材表面自由基浓度的变化规律,并力图揭示其变化机理.
Significant correlation existed between free radical concentration on wood surface and temperature. Changes of temperature resulted in deformation of wood surface,which induced the emergence of mechanical free radicals. The changes also affected the moisture transferring process in wood. The combination of the two processes made the relationship between the free radicals and temperature more complicated. The change regular pattern of free radical concentrations on wood surface was studied in the temperature range from - 196℃ to 180℃.
