| 摘 要： | 一、前言 处于干燥过程的含水木材需要外界不断地吸取热量,准确地测定这种热量,对于计算木材干燥的热效率和木质材料的加工有重要意义。由于木材中水和木材的结合状态与木材的含水率有密切的关系,因此测定木材中水份脱离时所吸收的能量,对于研究木材和水的结合状态也有一定的价值。

| Abstract: | By differential scanning calorimeter (DSC), the enthapy change was measured during the release of water in wood kept at a variety of moisture contents, When wood powder was heated at a constant rate of heating, thus calculating the differential heat of sorption and integral heat of wetting. In addition, this paper discusses the combination state of water in wood. |
