宣明历是唐代行用最长的优秀历法。它关于日月运动、交食的认识和计算方法比大衍历有进步,本文对它的定朔计算精度及现存的敦煌宣明历书作了研究。
Xuanming Calendar is an excellent calendar which was used for the longest period in Tang Dynasty. It has some improvements over the Dayan Calendar in the knowledgement and calculation of the movements and eclipses of the sun and the moon. A study about the accuracy of the calculation in true new moon is made, and the Xuanming Almanac on the scroll found in Dunhuang Caves is discussed as well in this paper.
