《甲种敦煌算书》的考校和释补

Research and Proofreading on Pelliot 2667-Tunhuang Mathematical Manuscripts

半个多世纪以前,李俨先生曾多次介绍和研究《甲种敦煌算书》,将其断为唐代作品而详加释补。该文在校读原件后,认为该写本残卷当属于北朝敦煌算书,并在充分肯定和全面评价前人释补工作的基础上,就原卷各题内容、运算细节和字体风格等方面加以辨析,重新校释,力求使这部一千四五百年前的珍贵文献展现原貌。

More than half a century ago, Mr. Li Yan had for many times introduced and inquired into Pelliot 2667-Tunhuang Mathematical Manuscripts, which he concluded to be produced in the Tang Dynasty and was explained and supplemented by him in detail. After reading and checking the original manuscripts, this paper holds that these fragmentary manuscripts should belong to mathematical works of the Northern Dynasty (386 - 581). On the basis of evaluating in an all-round way the work of explanation and supplementation by predecessors, it discriminates, proofreads and explains again the content of various exercises, details of operation and style of written characters so as to present the original look of this precious document that can be dated back to one thousand four or five years ago.
