在用现代天文计算方法全部检验的基础上,按照原文的分类统计和分析《宋史·天文志》各种天象记录的数量和特征。统计中将所有天象记录分为可计算检验和不可计算检验两大类,并计算了各种记录的错误率,大多数错误记录可以考出其原貌。搜索了天文志以外的宋代天象记录。
Checked by modern astronomical computation, all the astronomical records in Astro- nomical Chronicle of History of the Song Dynasty are analyzed and counted on the basis of their origi- nal categories. They are then sorted into two types: the type that can be computed and the type that cannot be computed. The rate of mistake is computed, and most mistakes can be known to reflect their original shapes. Other literatures are also looked into for astronomical records of the Song Dynasty.
