atomic emission line

Hence the spectrum is called a line spectrum; it is also called an atomic emission spectrum since it is produced by emission of light from excited atoms.

因此，这个光谱也被称为线光谱，也被称为原子发射光谱，因为它是由被激活的原子发出的光产生的。

A new method for determining trace-level copper ion was proposed based on flow-injection on-line preconcentration and microwave plasma torch atomic emission spectrometry.

基于流动注射-在线柱预浓集-微波等离子体炬原子发射光谱，对在线浓集测定流路和各种测试条件进行优选，建立了一种测定痕量铜的新方法。
