Hence the spectrum is called a line spectrum; it is also called an atomicemissionspectrum 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。

Methods:Use the Grating Spectrograph to take photograph of atomicemissionspectrum of unknown sample and make quantitative analysis Results:Quantitative determination of trace elements in nutriment.
The heavy metals were detected with atomic absorption spectrum, atomic fluorescence spectrum and plasma emission spectrum, 9 heavy metals were measured quantitatively.
