| 摘 要： | 对２５ｋｅＶ氮、氩离子束辐照尿嘧啶（ｕｒａｃｉｌ）引起其分子结构的变化分别进行了研究，通过紫外光谱的分析，得到了离子注入后尿嘧啶的残余紫外吸收曲线，富里叶红外光谱仪的分析，说明尿嘧啶受到了一定程度的损伤；茚三酮反应的测定证明了氮、氩离子辐照后的样品中均产生了新的化学基团氨基。

| Abstract: | The change of the molecular structure of uracil induced by 25 keV N and Ar ions implantation was studied. The Dose curve was obtained from the analysis of the ultravilet spectra. The induced damage was analyzed by FTIR. NH 2group was proved to be produce by N and Ar ion beam with the analysis of quite sensitive ninhydrin reaction. |
