- early spectral type 早光谱型
- HDE 226868 might be under- massive for its spectral type,which would make Cyg x-1 less massive than previously calculated. 从光谱类型看，HDE226868也许并没有那么巨大，这会使得天鹅座X－1的质量比原先计算的要小。

- The origins of stars of differing spectral types must be dissimilar. 不同光谱型星的起源必然是不一样的。
- The cluster contains no main sequence stars bluer than spectral type F, other than perhaps some of the blue stragglers, since the brighter stars of that age have already left the main sequence. 这个星团除了一些蓝掉队星外，没有光谱分类在F以上的蓝色主序星，因为这些较量的恒星都已经离开了主序带。
- As each historical figure or a certain type of person has an approximate spectral type, like sing, play music to the music, so called “types of facial makeup in operas”. 由于每个历史人物或某一种类型的人物都有一种大概的谱式，就像唱歌、奏乐都要按照乐谱一样，所以称为“脸谱”。
- A convenient classification of stars is based upon the observed sequence of spectral types. 一种实用的恒星分类法是基于测得的光谱类型序列。
- We started early in order to arrive before dark. 为了在天黑前到达，我们很早就动身了。
- The hot, massive, high-luminosity stars of spectral types O and B are not distributed uniformly over the Galaxy but are grouped into extensive, separate aggregates that have come to be called associations. O型和B型的大质量高光度热星在银河系中分布并不均匀,而是聚集成为分开的大星群,即所谓星协。
