星族合成方法及发射线星系核区中的恒星组分

Stellar Population Synthesis and the Stellar Populations in Nuclear Region of Emission-line Galaxy

论述星族合成方法对研究复合恒星体系的重要意义，综述了星族合成的三种基本方法，着重介绍了以星因光谱为样本的星族合成方法（CSPS）及其应用。最后，作为一个例子，我们利用CSPS方法给出发射线星系Mrk499谱的合成结果。

In this paper,We emphasis the importance of stellar population synthesis(SPS) method forstudying composite of stellar systems, and summarize three kinds of SPS methods. We especiallyintroduce the SPS method based on star cluster integrated spectra(CSPS) and its application.As a example, we apply the CSPS method to the emission -line galaxy Mrk499 spectrum andgive the CSPS results at last.
