Normally, the measured spectral line for the superheated iron atoms would show up as a symmetrical peak. 通常,所测得的超高温铁原子光谱线会显示出一个均匀的尖顶。
After a little argon was mixed, the breakdown voltage of discharge obviously decreased.The spectral line intensities of nitrogen molecules and nitrogen atoms increased. 在大气中加入少量氩气后,击穿电压明显降低,在相同电压条件下,氮分子光谱线和氮原子光谱线强度都增强。
A particular spectrum line corresponds to a certain definite light wavelength. 某特定的谱线就代表一个确定光的波长。
In astronomical situations, the natural line width is seldom directly observed. 在天文学研究中,谱线固有宽度很少能直接观测到。
