值得注意的是，两者列表给出的“二三均”最大值分别为2o48（《算书》卷三十五·月离表卷四“太阴二三均总数加减表上”，叶三十一；788：622—623）和2o4816（《考成》表卷四之二“二三均数表下之二”，叶二十；265：500） 4、应用“二三均”的8个推算公式，不仅可以得到《考成》的“二三均数表”（《考成》表卷三、卷四；265：419—523）、而且在“分”上取值得到《算书》“二三均总数加减表”（《算书》卷三十四、卷三十五；788：590—632 。 5、根据“月距诸率为地半径”、“地半径视差”和“月视径”数据，可以认定，《御制历象考成》所取的地球直径与月球直径之比约为3.72，不同于哥白尼的3.5，目前测定值为3= 6371.004km ×2 ÷3476.4km）。 6、《考成》交食理论基础是地平坐标系和黄白交角；与其相关的“表”卷六、卷七和卷八的几何计算公式得以复原。 Part 3 Discussion and Conclusions Related to YZLXKC Conclusions: 1. The characters of leap years in Xiyang Xinfa Lishu (1645), Kangxi Yongnian Lifa (1669) and Yuzhi Lixiang Kaocheng (1725) had a common continuity. 2. The theory of the lunar motion in Yuzhi Lixiang Kaocheng was based on the model of epicycle- oblique circle- sub-epicycle- sub-oblique circles (Benlun- Junlun- Cilun- Cijunlun). 3. The Ersan Junshu Biao in Yuzhi Lixiang Kaocheng, and Ersan Junshu Zongshu Jiajian Biao in Xiyang Xinfa Lishu as well, could be derived by the above mentioned model as the result of the eight calculating formula. Part 3 Discussion and Conclusions Related to YZLXKC 4. The Moon’s greatest distance from the Earth, the parallaxes of the Moon and the apparent diameters of the Moon in Yuzhi Lixiang Kaocheng were different from the values given by Claudius Ptolemaeus (c.90-168), Nicolaus Copernicus (1473-1543), Tycho Brahe (1546-1601), and Johannes Kepler (1571-1630). 5. The ratio of the diameter of Earth and the diameter of the Moon in YZLXKC is 3.72 and 1, which is different from the value of 3.5 and 1 given by Nicolaus Copernicus and appeared in Xiyang Xinfa Lishu. 6. The modern theory of the lunar motion, put forward in Issac Newtion’s 1702 Theory of the Moon’s Motion and the second edition of Principia (1713) was not introduced in YZLXKC, which was slightly revised and incorporated in Yuzhi Lixiang Kaocheng Houbian (The Supplement to Complete Studies on Astronomy and Calendar, 1723-2022).
