【摘要】:日影千里差一寸的觀念在中國(guó)天文學(xué)史上產(chǎn)生過(guò)深遠(yuǎn)影響。結(jié)合考古學(xué)和考古天文學(xué)的新發(fā)現(xiàn)和新的研究結(jié)論,并重新分析解讀相關(guān)歷史文獻(xiàn)的記載,得出日影千里差一寸的觀念當(dāng)產(chǎn)生于國(guó)家建立之際黃河中游兩個(gè)重要的考古學(xué)文化——堯都陶寺和禹都王城崗——的日影觀測(cè)實(shí)踐。這兩個(gè)地點(diǎn)觀測(cè)到的夏至日影分別為1.6尺和1.5尺,也就是《周髀算經(jīng)》和《周禮》所記載的兩個(gè)夏至日影長(zhǎng)度;通過(guò)對(duì)早期長(zhǎng)度和距離的分析證明兩地之間的直線距離接近當(dāng)時(shí)的1000里。這一時(shí)期正是中國(guó)文明史上日影測(cè)量和大范圍地理測(cè)量相繼開(kāi)始的特殊時(shí)期,由此產(chǎn)生了日影千里差一寸的理論觀念。
[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discoveries and new findings in archaeology and archaeological astronomy, and reinterpreting the records of relevant historical documents,It is concluded that the idea of a thousand miles difference of the sun shadow comes from two important archaeological cultures in the middle reaches of the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.
