【摘要】：敦煌具注歷日中,漏刻標注呈現(xiàn)的是晝夜百刻制。其中有關(guān)"二分二至"的漏刻標注,始終沒有出現(xiàn)在相應(yīng)的節(jié)氣(春分、秋分、冬至、夏至)日期上,這主要表現(xiàn)在具注歷日對晝漏50刻的標注往往要比春分、秋分節(jié)氣晚1—3日,而夏至?xí)兟?0刻和冬至?xí)兟?0刻的標注又提前了3—4日。另一方面,具注歷日所見一年的晝夜長短變化中,多數(shù)情況是每8日晝夜時長增減1刻。較為特殊的是,春分、秋分前后,晝夜長短變化中每增減1刻通常需要的時間是7日。相比之下,冬至、夏至前后漏刻增減的時間要稍長一些。具體來說,"二至"前晝夜時長增減1刻需要的時間是12日,"二至"后晝夜長短增減1刻需要的時間是18—19日。若與春分、秋分"加減速,用日少"的特點相比,大體比較符合《唐六典》"二至前后加減遲,用日多"的描述。
[Abstract]:Dunhuang notes throughout the calendar, the missing mark is presented day and night 100-scale system. The missing mark of "dichotomy" has never appeared on the corresponding date of the Spring Equinox, the Autumn Equinox, the Winter Solstice, the Summer Solstice. The Autumn Equinox solar terms are 1-3 days late, while the 60 day leaks in the Summer Solstice and 40 days in the Winter Solstice days are marked 3-4 days earlier. On the other hand, in the variation of the length of day and night of the year observed on the calendar day, most of the cases are increased or decreased by one quarter every 8 days and nights. More specifically, it usually takes 7 days for each diurnal change before and after the Spring Equinox and the Autumn Equinox. By contrast, the Winter Solstice, the Summer Solstice before and after the leakage increase or subtract a little longer. Specifically, it takes 12 days to increase or decrease one hour before "two to", and 18-19 days to increase or decrease the length of day and night after "two to two". If compared with the characteristics of the Spring Equinox, the Autumn Equinox, "increasing and decelerating, using less days", it is generally in line with the description of "add or decrease late before and after", "more days" in "Tang Liu Dian".
