我们简要介绍了研究星系演化的最重要的因素。特别是星星形成、核合成和气体流动的作用。然后,我们讨论了两种不同的方法来星系演化:恒星人口的方法(化学演化模型)和星系形成的等级聚类方案。它表明,仍然有一些有争议的点,在这两种方法,这是显而易见的,在简要的讨论摘要。
We are briefly introducing the most important ingredients to study galactic evolution. In particular the roles of star formation, nucleosynthesis and gas flows. Then we are discussing the two different approaches to galactic evolution: the stellar population approach (chemical evolution models) and the hierarchical clustering scenario for galaxy formation. It is shown that there are still some controversial points in the two approaches, as is evident in the brief summary of the discussion.
