The main results of the observation of quasars are shown as continuous spectrum, absorption linespectrum and emissionlinespectrum.
类星体的观测结果集中表现在三个方面：连续谱、吸收线和发射线。

Hence the spectrum is called a linespectrum; 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。

The line shape of measured emissionspectrum is proposed to be considered for calculating emission cross-sections at different wavelength.
