主　　题：ANCIENT ECLIPSE RECORDS OF CHINA AND EARTH’S ROTATION 

摘      要：This paper presents a collection of the time records of 87 solar and 72 lunar eclipses in ancient China (by the end of the Ming dynasty). According to the recorded times of the contacts (local solar time) and corresponding theoretical times (ephemeris time), the corrections of the universal time, △T are obtained. The results show that the scattering of the △T values is not large, its series can reflect the principal tendency of the secular deceleration of the earth’s rotation, and its deviation is obviously better than the results obtained from the central eclipses. Finally, the synthesized series of AT and Aω/ω and a brief discussion are given.
