摘要
《周髀》中存在"勾股量天"和"计算日影"两个传统,源远流长且影响深远。文章试图以这两个传统自汉至唐初的发展与演变为中心,探讨中国古代天文学中宇宙论与计算之间的关系。最初,《周髀》中的盖天说模型与计算是紧密结合在一起的。后来,随着历算技术的发展,特别是观测技术的提高,历法计算与宇宙论模型开始分道扬镳。自唐中期伊始,中国古代天文学进入相对成熟的阶段,一个主要特征就是宇宙论与计算之间是相互脱节的。
Calculating the heaven by using Gougu technique and computing the solar shadow, which were recorded in Zhoubi, had a long history and far-reaching implications. Centered on the two traditions from Hay dynasty to Tang Dynasty, this article tries to investigate the relation between the cosmology and computation in ancient Chinese astronomy. In Zhoubi, the doctrine of Gaitian cosmography and calendar computation was in concord with each other. Later, with the improvement of techniques of high accuracy in observing and computing, the computation and cosmology could not have been assimilated to formal character of Chinese astronomy as a whole. From the time of Middle Tang, as a major feature of entering a relatively mature state, Chinese calendrical science became indifference toward cosmographies.
