玄始历谱

Xuanshi Almanac

由赵欧创制、北凉首用、北魏继续沿用了111年（A．D．412～A．D．522）的玄始历，除《开元占经》收录了少部分数据外，其余推朔术、推气术、推闰术等，史籍概无记载．目前常见的历表，有的将北凉、北魏纪年加注在别国所用历谱之下，但大部分既无北凉、北魏纪年，又无玄始历谱．这对于历史学、考古学、北方民族史、少数民族科技史研究都是不适宜的．依据出土帛书、墓志、石刻等文物资料，参照《开元占经》所载数据，对玄始历谱进行了研究、排算和验证．

Except for Kai Yuan Zhan Jing recording a small part of data,Xuan Shi Almanac which was made by Zhao Fei,used firstly in North Liang Dynasty and used continuously for 111 years in North Wei Dynasty wasn＇t recorded in other history works. In ordinary calendars tables, there is no Xuan Shi Calendar of North Liang Dynasty,or it was attached at other calendars of other dynasties. It isn＇t appropriate for the research in history,archaeology and science history. The paper makes researches ,count and examination to Xuan Shi Calendar with history documents and data in Kai Yuan Zhan Jing.
