摘要

木材经γ辐照后，高聚物分子的共价键断裂而产生自用基。主谱g,0,=2.0193的自由基随辐射剂量D按指数率Y=1-e,αaD,规律增长，最后趋于饱和。辐射引发自由基强度与树种有关。机械自由基强度大的木屑，辐射引发自由基强度也大。

Abstract

The free radicals in wood induced by γ-radiation were studied by electron spin resonance. the fine structure of the ESR signal from sawdust samples irradiated could be resolved into various radicals. These free radicals have a very long lifetime. The major spectrum for the free radicals will exponentially increased along with the radiation dose according to Y=1 - Exp(-α,a,D). The intensity of radiation radicals is dependent on tree species. The stronger the intensity of mechanic free radicals is the stronger the intensity of radiation free radicals is.
