摘　　要：恒星形成是天体物理学的基本课题之一,而大质量恒星的形成与演化对研究银河系乃至宇宙的演化起着关键作用。目前对于大质量恒星形成的研究还处于不成熟的阶段。CO分子外向流的观测对研究大质量恒星形成过程及其对周围环境的影响具有重要的作用。文章结合国内外CO分子外向流的研究现状,对于CO分子外向流的观测方法和判断标准进行了介绍。Star formation is one of the basic issues of astrophysics. The formation and evolution of massive stars plays an important role in the study of the evolution of the galaxy and the evolution of the universe as well. The current status of research on massive star formation is still at an immature stage. The observation and research on CO molecular outflow plays an important role in the study of massive star formation process and its impact on the surrounding environment. In the present paper, observation method CO molecular outflows and the criterion of judgment were introduced based on the status of CO molecular outflows observation at home and abroad.
