摘要
In the aspect of examination by observations and based on a longer data span and improved precision of very-long baseline interferometry observations, the corrections to the IAU 1976 precession constant and the coefficients of IAU 1980 nutation series are solved. The corrections to coefficients of long periodic terms, the detection of the retrograde free core nutation, and the possible relation between the corrections to coefficients of the prograde annual term and the enviromental temperature are also briefly discussed.
