emission line spectrum 发射线光谱
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。
The main results of the observation of quasars are shown as continuous spectrum, absorption line spectrum and emission line spectrum.
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。
The line shape of measured emission spectrum is proposed to be considered for calculating emission cross-sections at different wavelength.
并建议通过发射光谱的实测线形计算各波长的发射截面。
