摘要：

The softening temperature of wood of spruce and birch has been studied by differential scanning calorimetry (DSC) over a range of moisture contents between 5 and 25%. An endothermic peak was observed in the first DSC scan. This peak is probably associated with the softening of lignin.The results in this study indicate, however, that DSC measurements on wood must be evaluated with great care. © 1990, Walter de Gruyter.
