摘要

对中国公元434-1280年的111次日月食计时和中东公元829-1020年的56次日月食计时的分析表明，它们的精度接近其时钟系统的极限分辨率。随着观测时间的推移，中国的准确度逐渐提高，标准偏差从公元600年左右的大约18分钟减少到公元1200年左右的7分钟。中东时间的标准偏差在公元950年左右为5分钟。

Accuracy of medieval Chinese and Middle-Eastern timings of eclipses

Analysis of 111 Chinese timings of solar and lunar eclipses in the period AD 434–1280 and of 56 Middle-Eastern timings in AD 829–1020 reveals that their accuracy approached the limiting resolution of their clock systems. The Chinese accuracy improved progressively over the period of observation, with the standard deviation reducing from approximately 18 minutes round about AD 600 to 7 minutes circa AD 1200. The Middle-Eastern timings have a standard deviation of 5 minutes around AD 950.
