对中国古代彗星记录的研究状况进行了全面论述。讨论了古代彗星名称、记录 和轨道的确定，以事实说明，据这些彗星记录不可能得到精确的轨道；回顾了古代彗星证认的 历史发展，着重分析进行短周期彗星证认时可能出现的问题和解决方法；总结了 古代彗星证认的意义：一是有助于短周期彗星长期演化的研究，二是有助于历史年代的 确定。
In this paper, the study of cometary records in ancient China is generally reviewed. The definition of cometary names and positions in ancient China is discussed, and it is pointed out that it is impossible to obtain their accurate orbit from the ancient records. The discussion on the method to identify short-period comets among cometary records in ancient China is emphasized. The meaning of identification of ancient comets is summarized: it is useful to study a long-term evolution of short- period comets and chronology.
