——对欧洲现存17世纪中西交流文献的考证 49385 摘要：本文通过对欧洲现存17世纪中西交流文献的研究考证，否定了莱布尼茨在发明二进制以后才见到先天图的说法。先天图在莱布尼茨发明二进制之前，已被斯比塞尔称之为二进制。从莱布尼茨的信中，可见先天图传入欧洲早于17世纪。 32885 关键词：先天图； 二进制； 莱布尼茨； 伏羲八卦图 17103 Had Leibniz not seen the Xian tian tu before he founded the binary system? 40840 —— A textual research of European literature about culture exchange between China and the West in the seventeenth century Abstract: Through a textual research of European literature in relation to the culture exchange between China and the West in the seventeenth century, this paper refutes a view that G.W. Leibniz had not seen Xian tian tu before he invented the binary system, for G. Spizel had already called Xian tian tu a binary system before Leibniz invented the binary system. By a letter of Leibniz, it is clear that Xian tian tu had spread into Europe before the seventeenth century.
