The chief calendric problemwas a gradually increasing discrepancy between the trueastronomical year and the Julian calendar then in use.

We tried hard to understand his astronomical work as a whole in order to discuss more thoroughly the reason of the failure of the Chinese traditional calendrical astronomy in the calendar reform in the late Ming Dynasty.

一些学者对明末传统历法复兴的有关问题以及邢云路的天文历法工作进行过研究和探讨，该文则将邢云路的工作看作一个整体放在明末传统天文学复兴和历法改革的背景中进行细致讨论，力图对他的工作形成整体性的认识，以期深入探讨传统天文学在明末改历中失败的原因。

Moreover, we can give a more embedded discussion to the reason of the failure of the Chinese traditional calendrical astronomy in the calendar reform in the late Ming Dynasty.

明末的历法改革首先在传统历法的范式内展开，而邢云路(1549-约1626)既是明末传统历法复兴过程中最为重要的人物，也是万历年间唯一一位有机会进入钦天监在传统历法范式内实施改历的民间传统历法家，因此对邢云路的天文历法工作进行研究可以让我们对明末的历法改革以及传统历法在其中的作用和表现有一个较为清楚的认识，也可以对传统天文学在明末改历中失败的原因进行更加深入的探讨。

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.

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。

Xing yunlu (fl. 1580-1621) was not only the most important person during the period of the revival of traditional calendrical astronomy in the late Ming Dynasty, but also the only civilian astronomer who had the chance to reform the traditional calendar in the official Astronomical Bureau of the Ming Dynasty from 1612 to 1621. By studying Xing Yunlu's calendrical classics, we can better understand the calendar reform and the action and represent of the traditional calendrical astronomy in the late Ming Dynasty. Moreover, we can give a more embedded discussion to the reason of the failure of the Chinese traditional calendrical astronomy in the calendar reform in the late Ming Dynasty.
