摘要
通过测定激光诱导等离子体中Ａｌ原子共振双线３９６．１５ｎｍ和３９４．４０ｎｍ强度的时－空演化特性，对激光诱导等离子体中共振双线的演化规律及其机理进行了讨论。使用的气体是空气，气压为１０１ｋＰａ。
Based the time and space resolved spectroscopy and the measurements of intensity of resonant double lines 396.15 nm and 394.40 nm from laser induced plasma, the time and space evolution characteristics of resonance double lines of aluminium in a plasma were obtained and mechanism was discussed. Air was used as surrounding atmospheres. The pressure was set up to 101 kPa.
