基于JPL行星历表的殷卜辞乙巳日食观测的研究

Research of Yisi Solar Eclipse Observation in the Oracle-bone Inscriptions of the Yin Dynasty Based on the JPL Planetary Ephemeris

对于殷商甲骨文卜辞中存在的唯一可考日食记载,利用美国航空航天局(National Aeronautics and Space Administration,NASA)喷气推进实验室(Jet Propulsion Laboratory,JPL)发布的DE422行星历表,解算了记载涉及此乙巳日食的主要参数,给出了日食带在地球上的覆盖范围。进一步确认此次日食在殷都安阳的可视性,验证了殷卜辞对此次日食预测的准确度。

For the only solar eclipse recoded in the oracle-bone inscriptions of the Yin dynasty discovered so far,the authors use the DE422 planetary ephemeris released by the Jet Propulsion Laboratory(JPL)of the National Aeronautics and Space Administration(NASA)to calculate the main parameters involved in the Yisi solar eclipse,give the coverage of the solar eclipse path on the Earth.Furthermore,the visibility of the solar eclipse in Anyang,capital of the Yin dynasty is confirmed and the accuracy of the Oracle-bone inscriptions about the solar eclipse of the Yin dynasty is verified.
