| 摘 要： | ＯＢ星协和年轻星团是恒星形成与早期演化的“化石”，同时也是研究初始重质量函数（ＩＭＦ）的最好场所；文中就ＯＢ星协和年轻星团的形成和早期演化方面的研究进展作了一评述，还论述了ＩＭＦ的测定和研究情况，并对相关的速逃ＯＢ星及蓝离散星问题作了简要介绍。

| Abstract: | OB associations and young star clusters are "fossils" of star formation and early stellarevolution. They are also the best sites to determine the initial mass function (IMF). Withthe application of many new observational techniques and methods, studied on OB associationsand young star clusters are very active recently. In this paper, developments on studies of theformation and early evolution of these very young stellar systems are reviewed. The determinationand study of IMF are discussed. Two related problems, i.e., run away OB stars and bluestragglers, are briefly described. |
