论二十八宿古距度在先秦时期的应用及其意义

该文认为《洪范传》古度和夏侯灶墓圆盘古度是古距度系统中两种不同类型的古距度。在此基础上，运用计算实证的方法，证明了古颛顼历、秦历《五星占》的行星观测使用的都是古距度，它的距星与传统距度的距星有巨大差别，提出只有在搞清古代天象观测使用何种距度和距星坐标的前提下，才能正确计算其观测年代的论点。

APPLYING AND SIGNIFICANCE OF THE OLD STAR-DISTANCE BETWEEN 28 CONSTELATIONS IN PRE-QIN ASTRONOMY

This treatise holds that the old star-distance of Explaining Hong Fan and the disc old star-distance of Xia Hou Zaotomb were two different types of old star-distance in oldstar-distance system. The authors of this paper, through calculating, have proved that the old star-distance was used in planets observation of the old Zhuan Xu calendar,the Qin calendar and Divining Face Planets and there is a great difference between the oldstar-distance and the traditional star-distance. The authors put forward that only when you know clearly which kind of star-distance and sign star coordinate was used in ancient observing the heavenly bodies, can you calculate the time of observing exactly.The authors pointed out the preat value of the old star-distance coordinate system in history of astronomy and the research of historical time.
