摘　　要：中国古代并无黄极的概念,所谓月亮距黄道南北的度数,实际上是沿赤经圈量度的,对此,日本薮内清教授有很精到的阐述,并称该度数为极黄纬。本文拟讨论中国古代月亮极黄纬计算的表格法和公式法的演进及其精度问题。In ancient China, the distance of the moon from the ecliptic north or south, which was called polar-latitude, was measured along the right ascension circle. From Liu Hong's Qian Xiang calendar (206) to Yi Xing's Da Yan calender (728) the lunar polar-latitude had been calculated by the table method. And the formula method, whose formulas were quadratic or quartic functions, came to be used in Bian Gang's Chong Xuan calendar (892) and in calendars of later periods. Our study shows that the errors of both methods are about 0.4.
