【摘要】：日影千里差一寸的观念在中国天文学史上产生过深远影响。结合考古学和考古天文学的新发现和新的研究结论,并重新分析解读相关历史文献的记载,得出日影千里差一寸的观念当产生于国家建立之际黄河中游两个重要的考古学文化——尧都陶寺和禹都王城岗——的日影观测实践。这两个地点观测到的夏至日影分别为1.6尺和1.5尺,也就是《周髀算经》和《周礼》所记载的两个夏至日影长度;通过对早期长度和距离的分析证明两地之间的直线距离接近当时的1000里。这一时期正是中国文明史上日影测量和大范围地理测量相继开始的特殊时期,由此产生了日影千里差一寸的理论观念。
[Abstract]:The idea of a thousand miles away from the sun has had a profound impact on the history of Chinese astronomy.Combining new discoveries and new findings in archaeology and archaeological astronomy, and reinterpreting the records of relevant historical documents,It is concluded that the idea of a thousand miles difference of the sun shadow comes from two important archaeological cultures in the middle reaches of the Yellow River at the time of the founding of the Yellow River-Yao du Tao Temple and Yu du Wang Cheng Gang-in the solar shadow observation practice.The daily shadow of the Summer Solstice was 1.6 feet and 1.5 feet respectively, which was the length of the two pictures recorded in Zhou Bi Sutra and Zhou Li >.By analyzing the early length and distance, it is proved that the distance between the two places is close to 1000 miles.This period is a special period in the history of Chinese civilization, in which the sun shadow survey and the wide range geographical survey began one after another, and the theoretical concept of "one inch" difference between the sun shadow and the "shadow" came into being.
