《七正推部》(1477年)中的10个行星经度表中的偏心率和半径模型以及计算公式已被完全概述。托勒密行星理论已应用于这些表格的编制中,并对参数和变量进行了轻微修改。 《七正推部》相对表中的第一个高级行星方程(aequatio centri)与《天文学大成》中的q(cm)相同。金星第一个方程的值与七正腿部中心的太阳方程相同。水星第一个方程的模型与托勒密偏心率相同,但半径不同。土星的比例变量是中心角的平均变量,木星、火星和金星的中心角是真实的角,水星是特殊的中心角。第二个方程 (aequatio argumenti) 的变量 p 是异常的真实参数,与异常 p(am) 的平均参数的托勒密选择不同。 《Sanjufīnī Zīj》(1366)第 47v 至 52r 的 10 个表格,没有《七正推部》中的 q(n+1)-q(n)、p(n+1)-p(n) 栏,已得到解释。
The models with eccentricities and radius, and the calculation formula underlying in the 10 planetary longitude tables in the Qizheng Tuibu (1477), have been completely outlined. Ptolemaic planetary theory has been applied in the compilation of these tables with slightly revision of the parameters and variables. The first equation (aequatio centri) for the superior planets in the relative tables in the Qizheng Tuibu is the same as q(cm) in Almagest. The values for the first equation for Venus are the same as the solar equation of the center in the Qizheng Tuibu. The model of the first equation for Mercury has the same as Ptolemaic eccentricity but with different radius. The variable for proportion of Saturn is the mean argument of center, of Jupiter, Mars and Venus is the true argument of center, of Mercury is a particular one. The variable for the second equation (aequatio argumenti) p is the true argument of anomaly, different from Ptolemaic selection of the mean argument of anomaly p(am). The same 10 tables from 47v to 52r of the Sanjufīnī Zīj (1366), without the columns for q(n+1)-q(n), p(n+1)-p(n) in the Qizheng Tuibu, have been explained.
