| 摘 要： | 分别轻注入机和气体常压孤光放电产生的你了子作用于固态和溶液中的氨基酸，研究了样品红外光谱的变化。结果表明，两种方式产生的离子对氨基酸有相同或相似的损伤作用，如分子重排、外来离子沉积等，而且低能离子作用于溶液样品表现出更显著、更丰富的损伤效果。

| Abstract: | Low energy ions have been generated from implanter and gas arc discharge at normal pressure,and impacted on amino acids in solid state and in aqueous solution.The induced changes of infrared spectra have been investigated.It showed that ions generated by these two means have the same or similar damage effects,such as rearrangement of damaged molecules and deposition of external ions,and the damage effects are especially remarkalbe and various when ions attack molecules in solution. |
