《周髀算经》盖天宇宙结构

长期以来，《周髀算经》盖天宇宙模型中的天地形状一直被认为是双重球冠形，并将这一点视为《周髀算经》“自相矛盾”之处。本文通过对《周髀算经》全书的系统分析，从演绎体系、数理结构、语词辨析等多方面论证了“双重球冠说”之误。再进而给出了《周髀算经》盖天宇宙模型的正确结构和形状－新给出的结构和形状在全书中非常自洽。

THE ACCURACY OF THE COSMIC STRUCTURE IN ZHOU BI SUAN JING

The figures of Heaven and Earth in Zhou Bi Suan Jing (The Arithmetical Classic of the Gnomon and the Circular Paths) have all along been considered as a two-tier crown. So the work is always deemed self-contradictory in its structure of the universe. In this paper, the author shows that the so-called "two-tier spherical crown"is absolutely in the wrong due to the misunderstanding of some words in the text of the work. Figured in the paper is an accurate cosmic structure of Zhou Bi Suan Jing, which is reconcilable in the work's entire text.
