line spectra

The results show that the spectra of laser-induced plasmas for the three kinds of gas samples are composed of continuous spectra and line spectra, the basic features of the continuous spectra and line spectra were given, the possible connection.

结果表明 ,各种气体样品的激光等离子体光谱均表现为连续谱和线状谱的叠加 ,文中分别给出了连续谱和线状谱的基本特征 ,讨论了这些特征与等离子体物理特性的关系 ,并分析了纯氮、纯氧与空气激光等离子体光谱之间的异同。
