摘　　要：本文对三种具有代表性的国产光纤的γ辐照感生损耗效应进行了研究,得出在0.85μm 波长感生损耗随辐照剂量变化的规律。利用电子自旋共振(ESR)技术对辐照光纤的缺陷进行了研究,并对缺陷形成的过程和机制进行了分析和讨论。Research is carried out on the effect of γ-ray irradiation-induced damage for three kinds of typical fibers made in home.The regularity is given of variation of induced damage with the irradiation dose at 0.85μm wavelength.The defect in irradiation fiber is studied using ESR technique and the formation process of defect is analysed and discussed as well as its mechanism.

关 键 词：光纤 γ辐照感生损耗 电子自旋共振 缺陷机制
