| 摘 要： | 银晕外区存在众多的星流，它们或源自银河系的矮伴星系，或源自球状星团。星流可以利用各类示踪星，并通过不同的途径来加以研究，对于探索银河系演化史和银河系暗晕的形状具有重要意义。

| Abstract: | Many stellar tidal streams in the outer halo of the Milky Way Galaxy have been found since 1994. Some streams are formed from dwarf satellites and others from globular clusters. More and more observational and theoretical studies on the stellar streams have been done during recent 20 years or so, from which some important results were gained. |
