摘　　要：介绍了国际上对氩第三谱带的实验和理论研究工作。实验上 ,采用不同的泵浦方式 ,观察了荧光谱的谱带形状 ,并对时间分辨谱进行了测量。理论上 ,通过光谱学和动力学两方面的计算 ,对氩第三谱带的来源进行了研究。目前主要有两种假设 ,即Ar2 2 +和Ar2 +离子准分子的跃迁产生该谱带。但这两种假设都只能解释部分实验现象 ,因而谱带的来源至今没有确切的结论。In experiment and theory,the studies on the thi rd continuum of argon in the word are introduced In experiment,with different pumping ways,the shape of fluorescence and time resolved spectra are measured Up to now the small signal gain of this continuum has been reported In theory ,with the calculations of spectrum and kinetics,the origin of the continuum is studied There are two main hypothesis that the continuum can be emitted by the transition of Ar 2 2+ and Ar 2 + ionic excimers Because either of the two hypothesis can only interprete a part of experimental results,there are no identical conclusions about the origin of the third continuum
