摘　　　要

介绍了银河系中各种化学元素丰度随金属丰度的变化规律。结合恒星核合成理论，可以了解银河系的形成和演化过程。另外，某些化学元素丰度存在的弥散可能是恒星形成时银河系环境的不均匀性造成的。

Abstract

Abundance patterns of the various elements from the very light to heavy in our Galaxy are introduced and reviewed. These patterns combined with the stellar nucleosynthesis theory enable us to study the formation and evolution of the Milky Way. The abundance scattering of some elements is probably due to the inhomogeneous environment in our Galaxy.
