| 摘 要： | 观测显示星系中的大部分恒星是双星，因此星族合成研究必须考虑双星的作用。综述双星对星族合成研究的重要性。主要讨论了双星对早型星系和球状星团的能谱、谱指数、颜色、颜色一星等图、星系参数确定和恒星形成历史研究的影响。主要结论为双星有助于对星系和星团的光谱、颜色一星等图的解释，以及对星系和星团多个参数的准确确定。因此，双星是准确星族合成研究的必然要求。

| Abstract: | Observations show that most stars are in binaries, which indicates that binaries should be taken into account in stellar popu- lation synthesis studies. This paper reviews the importance of binaries in the studies of stellar populations. The effects of binaries on the spectral energy distributions, line strength indices, colours, colour-magnitude diagrams, parameter determinations, and star forma- tion histories are discussed. The review shows that binaries are very helpful for the explanations of spectra and colour-magnitude dia- grams of galaxies and star clusters, and they also affect the determinations of many important parameters. Therefore, the inclusion of bi- naries is a natural trend for future stellar population studies. |
