漏水轉(zhuǎn)渾天儀
In the middle of the Eastern Han Dynasty, Zhang Heng,an outstanding astronomer, made bold innovations to the armillary sphere,and de-signed and made the first water-driven armillary sphere in the world to measure the position of celestial bodies,which was carved with known important astronomical phenomena. People could observe the movement of the sun,the moon and the stars.
漢中期,杰出的天文學(xué)家張衡對渾儀作了大膽創(chuàng)新,設(shè)計并制作了漏水轉(zhuǎn)渾天儀。張衡還制造出了世界上第一架測量天體位置的水運(yùn)渾天儀,凡是已知的重要天文現(xiàn)象,都刻在這架儀器上。人們可以通過渾天儀觀測到日月星辰運(yùn)行的情況。
