Shicha algorithm of parallax theory plays an important role in solar eclipse theory because it is one of the major algorithms in solar solar eclipse theory 摘要日食時差算法是日食計算中的核心算法,在日食理論中占有重要地位。
After studying the shicha algorithm of parallax theory in shoushi calendar and huihui calendar , this paper points out that shicha algorithm in huihui calendar is better than that of shoushi calendar about the completeness of variables , the choice of the sign of shicha and the procession of shicha algorithm , thus concluding that it can help us to evaluate objectively the solar eclipse theory of ancint china and arabia 對《授時歷》和《回回歷法》中的時差算法進行比較研究表明, 《回回歷法》中的時差算法在自變量的完備性、符號的選擇以及精度等方面,均明顯優(yōu)于《授時歷》 ,該結論對評價中國和阿拉伯傳統(tǒng)日食算法優(yōu)劣有一定參考意義。
