【摘要】 银河系自转曲线给出银面上的圆周自转速度对银心距关系的信息,它反映银河系运动学特征,是研究银河系结构的基本工具. 本文评述了确定银河系自转曲线的原理、方法和结果,并分别对太阳圈以内、以外和银心三个部分作了介绍。最后对这个领域的研究进展,确定曲线中的误差来源以及尚待观测验证和理论分析的有关银河系运动学问题作了总结。更多还原

【Abstract】 This paper gives a general review on the principle, methods and results of deter. mining the rotation curve of our Galaxy. The topic is broken down into three subto-pics: the rotation curves inside, beyond the solar circle and round the galactic center. In the last part, progress of the study, error sources in the determinations, as well as some aspects of kinematic problems which need further observational examinations and theoretical analyses are summarized.更多还原
