摘要
该文根据其作者提出的关于木材细胞壁无定形区域中吸着水的介电弛豫机构模型，就木材细胞壁无定形区域中吸着水的束缚能Ｕ和活化焓ΔＨ，束缚能Ｕ和含水率Ｗ之间的相关关系，束缚能的定量表达式，吸着水的总势能等方面作了一些讨论．在此基础上，依照ＫｉｒｋｗｏｏｄＦｏｕｓ理论，从Ｓｍｏｌｕｃｈｏｗｓｋｉ方程出发，建立了描述在介电弛豫过程中，木材细胞壁无定形区域中的吸着水分子切断同木材吸着点之间形成的氢键结合进行回转取向运动的扩散方程．同时。
According to the model of dielectric relaxation organization, the author offers about water adsorbed on wood.This paper involves in some researches for relations between the tied energy of absorption water and enthalpy of activation,and the energy and moisture content;the mathematical formula of tied energy;the total potential energy of absorption water and so on.Based on this,following the theory of Kirkwood Fouss,beginning from Smoluchonski equation,the author establishes the diffusion equation that describes reorientation of absorption water in dielectric relaxation process,and discusses the form solution of the diffusion equation in special state.
