摘　　要：唐代天文学家瞿昙悉达编译《九执历》,介绍了古代印度天文学中 360°圆周分度体系,这是西方分度体系首次引入中国。尽管《九执历》中缺乏相应的角度概念,它的引入还是对改进当时中国的天文历法计算起到了一定的作用,但并未使中国原有的角度测量发展成为角度计量。通过梳理瞿昙悉达所做的工作,分析了360°分度体系未被中国人接受的原因,考察了它在天文学和数学上产生的影响。以及对计量史研究的意义。Gautama Siddhartha, who was an astronomer in Tang Dynasty, translated and compiled the Jiuzhi Calendar. He introduced the 360° circumference division system into China for the first time. Despite there was a lack of the corresponding concept of angle in the Jiuzhi Calendar, the introduction of 360° division system effected the improvement of the calculation in contemporaneous Chinese calendrical astronomy. But this did not turn the Chinese angle measurement into the angle metrology. By reviewing Gautama Siddhartha＇s efforts , the reasons why the 360°division system were not accepted in Tang Dynasty are analyzed, and special emphasis is laid on the research of its effects on astronomy and mathematics as well as its significance for the study of metrology history.
