摘　　要：该文在归纳高能射线的种类和高能射线辐射对木材作用机理的基础上 ,详细地归纳了高能射线 ,特别是γ射线辐射对木材构造和木材化学、物理、力学性质的影响 .本质上 ,当射线辐射剂量较高时 ,将引起木材细胞壁结晶度降低 ,细胞壁主成分分子链切断 ;当射线辐射剂量较低时 ,可能导致细胞壁主成分产生交联 .在此基础上 。This paper describes the main influence of high-energy rays, especially γ-ray irradiation on structure and chemical, physical and mechanical properties of wood. In fact, high doses of γ-ray irradiation will lower the crystallinity of wood and cut the chains of wood components, while lower doses of γ-ray irradiation perhaps lead to the formation of crosslinks between the cell wall polymers. Meanwhile, some ideas are given for fixing wood set and for studying the mechanism of permanent fixation of wood set using high-energy rays at the end of this paper.
