摘　　要：根据《崇天历》的日食计算方法,使用《乾道历》的天文常数,将南宋乾道九年五月朔的日食进行复原。严格按照历法推算日食的过程,将《乾道历》推算日食的每一个计算步骤与结果完全呈现出来。分别给出完整的每日太阳数据,计算定朔、日食食甚、日食食分和日食食延的公式。结合1173年6月12日的真实日食,分析《宋史》记载的乾道九年五月朔日食的观测与推算记录。结果表明,史载乾道九年的日食观测与实际天象不符,日食推算也与复原结果存在差异,这其中的原因还需进一步研究。By using the astronomical constants in qiandaoli calendric system and the calculation method of the solar eclipse in chongtianli calendric system,the solar eclipse of the fifth month of the lunar year of the Ninth Year of Qiandao period was restored.According to the process of calculating,each calculation step and results of estimating the solar eclipse of qiandaoli calendric system were given completely.Respectively,the complete solar data of each days were given,with the formulas for calculating the real new moon,middle of an eclipse,magnitude of eclipse and the interval of eclipse given.In combination with the real solar eclipse on June 12,1173,this paper analyzed the observation and calculation of the solar eclipse record on the fifth month of the lunar year of the Ninth Year of Qiandao period recorded in the History of the Song Dynasty.The results show that the solar eclipse observation in the fifth month of the lunar year of the Ninth Year of Qiandao in history is inconsistent with the actual celestial phenomena,and the calculation of the solar eclipse is also different from the recovery results.The reasons for these needs further study.
