| 摘 要： | 分析了历代历法设立“没限”与“灭限”的造术意义，纠正了以前的研究者对“没限”的误解。论证了唐代一行以“朔分所虚为灭”重新定义“灭日”，是为置闰算法而引入的概念，与推朔日日名无关。根据一行之后关于“没日”与“灭日”的定义，导出了置闰公式：闰月数＝（没日数＋灭日数）／３０。

| Abstract: | The limits of Mo and Mie are two parameters which were used to indicate in which period there should be a day of Mo or Mie.It is analysed how such parameters were constructed and corrects a misunderstanding of the limit of Mo.The notion of the Mie was changed to difference between 30 days and a synodic month after the Dayan Calendar (724 A.D.).This change is for calculating the intercalation,having nothing to do with the calculating of a new moon.According to the definitions of Mo and Mie after the Tang Dynasty,a formula of intercalation is derived as follows:the number of intercalary month=(the number of Mo the number of Mie)/30. |
