摘　　要：银心是离我们最近的星系核，它属于活动低下的典型星系核，对它的研究不仅是银河系结构研究中不可缺少的一环，而且是研究黑洞和活动星系核的极好样本。简要回顾了近10年对银心观测和研究的主要结果，并对银心的基本构造和组成，特别是对射电源SgrA及其银心暗天体的性质和模型作了比较全面的概括和总结。The Galactic center, the nearest galactic nucleus, represents the typical ones with low activity. Investigation of its nature and structure is important not only for the researches of the Galactic structure, but also for the study on black holes and AGNs. In this review, we briefly summarize the results of the observations and researches on the Galactic center in the past decade, including its overall structure and main components, especially the physical properties of the central compact radio source SgrA~* and the models of the central dark object.
