| 摘 要： | 运用比较研究的方法，对中国东汉四分历前后和古希腊首次出现的一些球面天文学概念以及黄赤交角的测量和计算进行比较．结果表明，东汉时期已经初步尝试并基本建立了一个空间天球概念，但是没有被启代很好地继承下来，而古希腊建立的空间天球概念被现代天文学所继承；古代中西方对于黄赤交角的测量和计算方法不同，并且东汉时期黄赤交角测量值的精度高于古希腊测量值的精度．

| Abstract: | The concepts of spherical astronomy and the observation and calculation of the angle between ecliptic and equator in the Donghan Dynasty and the ancient Greece were compared.The results showed that the astronomers in the Donghan Dynasty had already tried to erect a concept of celestial sphere in the space,but that didn't succeed by the afterworld.However,the concept of celestial sphere in the space erected by the ancient Greek had been succeeded by the modern astronomy.The methods of observation and calculation to the angle in Donghan Dynasty and ancient Greece were different,and the precision in the Donghan Dynasty was higher than that in the ancient Greece. |
