摘　　要：利用UV、HPLC、GC、GC-MS、GC-FT-IR等分析仪器对中能^(18)O^(8+)离子辐照胸腺嘧啶N_2O饱和水溶液进行了分析,对羟基加成产物、二聚体等十几种产物进行了鉴别,计算了各种产物的G值,对重离子辐照与γ射线辐照的结果进行了比较,最后对重离子作用机制进行了探讨.The products of thymine (T) irradiated by 18O8+ ion beam in N2O saturated aqueous solution was studied. The apparatus of Ultraviolet spectrometiy (UV), high perfonnance liquid chrornatography (HPLC) , gas chromatography (GC) , gas chromatography-rnass spectrometry (GC-MS) and gas chromatography-Fourier transform infrared spectroscopy (GC-FTIR) were used to analyze the products. The hydroxy and hydro adducts and dimers were determined. The G values of products were calculated. The damage of the irradiation of heavy ion beam was more serious than the irradiation of 7 ray. The mechanism of the irradiation of heavy ion beam on materials was also discussed.
