“阴阳象数图”之源流探析

Explanations on Origins of Yin-Yang Image-numberology in Mathematical Treatise in Nine Chapters

《数书九章》中有一张"阴阳象数图",它是秦九韶占筮方法的理论根据.关于该图的来历和出处,目前尚无定论.文章通过对宋代"先天易"学理论的考究与分析,结合今人对秦九韶生平的研究,对这一问题进行了探讨.认为:"阴阳象数图"是秦九韶自创的,而其理论根据则直接来源于"先天易"中的"阴阳象数"学说.

The diagram, Yin-Yang Image-numberology, in Mathematic Treatise in Nine Chapters is the theoretical basis of the divining method by Qin Jiushao. There has been no certain conclusion about the origin of this diagram yet. Through the analysis of Yi Jing in the Song dynasty and the whole life of Qin Jiushao, the paper has done much research and points out： Yin-Yang Image- numberology was created by Qin Jiushao himself and its theoretical basis came directly from the theory of Yin-Yang Image-numberolo- gy in Yi Jing.
