原子发射光谱

The spectra of stars and galaxies almost always show a series of discrete lines that form when certain atoms or molecules emit or absorb light.

星体和星系的光谱几乎总是表现出一束不连续的线，这些线形成于某些原子或分子发射或吸收的光线。

The relationship between spectral line intensities from different species in the plasma and neutron yield and shot number shows that: with high neutron yield, the deuterium ionization degree is high; nitrogen and oxygen atoms are also ionized to a higher ionization state; electron beams emitted at the collapse time of plasma pinch column may cause strong electrode sputtering processes.

可见光谱中氘、金属材料Cu、Fe和空气成分O、N的原子或离子谱线强度与中子产额和放电次数的关系证明：中子产额高时，氘气的电离率高，N、O等杂质气体也被电离到高电离态，焦点箍缩柱崩溃时发射的强电子束可以引起强电极溅射过程。

By means of time-resolved laser-induced fluorescence spectroscopic technique, two samples of Er3+∶YAG with 10.5% and 8.4% concentrations were resonantly excited with ultraviolet lasers at 262 nm and 276 nm, and the fluorescence spectra were recorded and the peak transitions were assigned in detail.

利用时间分辨激光诱导荧光光谱技术，用262 nm和276 nm紫外激光对原子数分数为x(Er3+)=10.5%和x(Er3+)=8.4%两种情况下Er3+∶YAG晶体的4D5/2和2H9/2能级分别共振激发，记录了每种情况下的荧光发射谱，对其中所有荧光谱峰对应的能级跃迁做了详细标定。

The most accurate observations are made when we observe the light emitted when the vapour pressure is low.

当蒸气压很低时，可以对原子所发射的光谱作出最精确的观测。
