摘要
在我国古代历法中,对太阳视赤纬的测算与晷漏、交食、日月五星位置等课题的研究密切相关,它是我国古代历法的基本算法之一。太阳视赤纬测算法的创立始自东汉四分历,自此以后,历代大多数历法均具此法,它们经历了表格计算法、公式计算法及表格、公式联合计算法等的历史嬗变。本文拟讨论这些算法的发展脉络,并对它们所达到的精度水平作出初步评价。
In ancient China, there were three methods for the calculation of solar apparent declination: the table method, the formula method, and the method of a combination of the two. As compared with the calculation of Western countries, it had its indepedent development in a special methematical way. According to our study, the error of calculation of all the three methods was only about 0.°1.
