实验结果显示，PEO接枝水凝胶膜的凝胶分数主要依赖于辐射剂量和聚合物浓度。
The experimental results showed that gel fraction of the PEO graft hydrogel films depended mainly on irradiation dose and concentration of the polymers.
结果低剂量率辐照所致的细胞存活分数比高剂量率辐照所致的细胞存活分数高。
Results The cell survival fraction of low dose rate is higher than that of high dose rate.
结果显示，PEO R-150溶胀水凝胶膜的交联密度随辐射剂量的增加略有增加，但无统计学意义（P>0.05）；聚合物质量分数对其交联密度的影响无显著性差异（P>0.05）。
The experimental results show that the irradiation dose and mass fraction ofthe polymer do not produce a significant effect on the gel fraction, of the PEO R-150 water-swollen hydrogel films(P>0.05).
