摘要
本文研究了几种类型电极,在垂直或水平电场方式下对火焰中钠原子的激光增强电离(LEI)信号的收集作用,并观察了诸参数(激光束位置、电极高度、电极间距)在不同电场方式下对信号的影响。
The laser-enhanced ionization (LEI) signal results from a change in flame impedance produced by collisional ionizaiton of laser excited anaiyte atoms. The purpose of this investigation was to the effects on LEI signal collection with different species of electrode cofifigurations in the vertical or the horizontal electric field system, and the effects of arameters on the LEI signal have been observed.
