| 摘 要： | 2005年在山西襄汾陶寺镇发现了世界上最早的天文观象台遗址——陶寺观象台,它呈扇形结构,主要由1个观测点和东侧的12条观测缝组成。为考察其作为古观象台的必要条件,借鉴现代实测方式,采用计算机系统对其在BC 3000—BC 1000年间作日切山顶的模拟观测,结论是该观象台可能的观测年代应早于BC 1500年,且最佳观测年份为BC 1956年,12条缝能观测21次,平均每缝的观测误差为0°.11,最大误差0°.7。观测日期与邻近节气的平均误差为4.5日。指出:观象台的观象目的可能是对陶寺文化中特定的时节(也许是处于萌芽状的节气)进行观测,亦或用以提供进行祭祀等重要活动的时刻。但由于该遗址的地表部分不存,已知信息有限,故难作准确推论。

| Abstract: | Taosi Observatory,possibly the earliest observatory possibly in the world,was found in 2005 in Taosi Town of Xiangfen City located in Shanxi Province.It has a sector structure and consists of one observing center and twelve observing slots.In order to investigate its essential conditions as a typical ancient observatory,and by referring to modern observations to imitate ancient works on this site,the contemporary astronomical system are employed to simulate the scheme when the sun just rose from behind the ... |
