摘　　要：利用介质阻挡强电离放电的物理方法,在窄放电间隙内获得超强电场,在常压下将N2分子电离、离解,形成N2+、N+等离子,注入乙酸钠样品,引起其分子结构的变化.通过水合茚三酮反应分析,证明了离子注入后乙酸钠样品中产生了新的化学基团α-NH2.同时紫外光谱的分析进一步证实乙酸钠样品在离子注入后发生了明显的分子结构变化.N2 molecules are ionized and decomposed into N2+ and N+ at ambient pressure on the effect of strong field in the narrow discharge gap by dielectric barrier discharge. And a number of the ions are implanted in the samples of sodium acetate which result in the changes of molecular structures. New radicals of α-NH2 are generated in the samples after the implantations, which is proved clearly by the color development reaction with ninhydrin. In addition, ultraviolet spectroanalysis further indicates the obvious changes in molecular structure after the implantations. 
