朝鲜奎章阁本的《授时历立成》

SHOU SHI LI LI CHENG IN THE VERSION OF KUI ZHANG GE OF THE CHOSON DYNASTY

立成表是古历中推算日、月、五星运动时，为简化计算所造的表。元代《授时历》是中国古代历法的巅峰之作，可惜《元史·历志》中没有收录它的立成表部分。在韩国保存有署名王恂的《授时历立成》奎章阁本１册。该文对这册立成表的内容进行了分析和研究，证明它确是在元代所做，其刊行时间为朝鲜世宗时代，具有珍贵的史料价值；而且，其中出现的四暗星内容对于《授时历》本身的历法内容是一个重要的补充。

Li Cheng Biao (ready reference astronomical table) in ancient calendars was made in order to simplify the calculation of the motion of the sun, the moon and the five planets. Shoushi Calendar of the Yuan Dynasty is the most advanced ancient Chinese calendar. However, the part of Li Cheng Biao was not included in the Records of Calendar of the History of Yuan Dynasty. In Korea, there exists Shou Shi Li Li Cheng(《授时历立成》)in the version of Kui Zhang Ge(奎章阁). After investigating this book, it is proved in this paper that the book was written in the Yuan Dynasty and re published in the reign period of King Sejong during the Choson Dynasty. Furthermore, the part of si an xing (four dark Stars) in the book is a very important supplement to the original Shoushi Calendar.
