康熙时代西方数学的传入及其对中国数学发展的影响，是中西数学交流史的重要课题。在以往工作的基础上，本项目将借助多年搜集的中西方数学典籍、档案史料等各类文献，采取算法分析、文献互证等方法，对这一课题展开新的研究。本项目不仅探讨康熙时代西方数学在宫廷的传播，分析来华耶稣会士和中国算学家在康熙时代数学传播与研究中的不同作用，并将进一步讨论传入的西方数学所产生的深刻影响，阐明乾嘉时期传统算学研究与西方数学，以及经学和历算研究的相互关系。通过对不同时期、不同地区数学发展的比较研究和具体案例的讨论，更为深入、全面地讨论明清时代西方数学在中国的传播情形，以清晰揭示中国数学近代化的历史脉络与不同面相。

The introduction of Western mathematics during the Kangxi reign and its influence on Chinese mathematics is an important issue in the history of Chinese mathematics. Based on former studies, this project will conduct a new research by comparing newly acquired Chinese mathematical texts, Chinese archival documents and collected writings of Chinese scholars with Western mathematical texts, and will investigate the transmission of European mathematics at the imperial court, analyse the roles the Jesuits and Chinese mathematicians played in the compilation of mathematical texts. In addition, it will discuss the profound impact of Western mathematics on Chinese mathematicians of Qianlong-Jiaqing period who used it as a tool to reinterpret the Chinese traditional mathematical texts. By a systematic comparison of the transmission in different periods and different regions, the project attempts to understand deeper the different aspects of the introduction of Western mathematics and the modernization of Chinese mathematics in its broader social context.
