摘要 演化的星族合成方法是在给定恒星形成率和初始质量函数的前提下,利用理论的恒星演化轨迹和恒星光谱库得到的组合特征(光谱,光度),拟合星系、星团等恒星复合天体的观测特征,给出其中星族组成的一种有效方法。对演化的星族合成方法在天体物理研究中的重要意义及其原理和算法以及影响演化星族合成方法结果的最主要的四个输入量:恒星演化轨迹、恒星光谱库、初始质量函数和恒星形成率进行了评述。 We introduce the importance, the principle and algorithm of evolutionary population syn- thesis method in the astrophysics field. The most four important ingredients in the method, the library of stellar evolution models or the tracks of stellar evolution, the library of stellar spectra, the initial stellar mass function and the star formation rate, are described. Finally, we have some comments on the method.
