摘　　要：本文介绍了星团颜色-星等图研究的新方法——双星复合星族合成,该方法通过加入双星星族来构建理论模型,并且考虑了多次星爆形成恒星的复合情况.通过使用该方法构建出来的几种理论星团颜色-星等图的例子可以看出,这些图形更加符合实际观测到的结果,因此,双星复合星族合成将成为研究星团颜色-星等图的新趋势.最后,简单介绍了它在研究星团颜色-星等图中的应用.In this paper,a new method of color-magnitude diagrams of clusters,i. e. binary-star composite stellar population synthesis,is introduced. This theoretical model is constructed by taking binary-star stellar and many starbursts into account. We give some examples of the theoretical color-magnitude diagrams of clusters and have found that they are more consistent with the actual observation results. Therefore,binary-star composite stellar population synthesis will become a new trend for the study of color-magnitude diagrams of clusters. At last,the applications of this method in color-magnitude diagrams of clusters are also briefly introduced.
