天干地支相配构成六十个甲子。按甲子律及十二地支闭合循环图，以阐明其变化规律，同时，提出了行列，给每个甲子以准确定位，并把甲子、行列、序号有机地联系在一起，制出了崭新的干支纪年表。文章还提出余数定理，使甲子量化，准确纪年。

The Heavenly Stems and the Earthly Branches can be used to pair in a definite order and combine in a cycle of sixty years.

We also organized the sixtyyear, the ranks and the numbers together to make a new calender based on the Heavenly Stems and the Earthly Branches.
