摘要
“朔”简言之表日月黄经相等，先民对其认识经历了一个从平朔到定朔的过程。通过研读古历，文中分析并归纳了不同时期中国古历日制度的基本元素之一──朔的两种推步方法：“积年法”和“《授时历》法”，其中包括平朔、日躔、月离、及定朔的推步方法等；得出了由各历的基本历数直接推出的中国古历定朔计算的一般公式；同时亦给出了《授时历》的推朔法和部分算例。
Shuo' (the new moon), one of the fundamental elements of the Chinese ancient calendars,was known first as the mean one and then clearly as the real one. By studying these calendars,this paper analyses and induces two kinds of the calculating method of 'Shuo' in different times (so-called 'Ji Nian Method' and 'Shou Shi Calendar Method') including the methods for computation of the mean new moon, the motions of the Sun and the Moon, the real new moon and etc. Using the basic data of each calendars, this paper also obtains straightly the general formulae of the calculation of the real new moon and gives some examples of Shou Shi Calender Method.
