摘要：
The components U-0 and Y-0 of the solar motion and the Oort constant A(0) are determined using the data of a homogeneous open-cluster catalog with corrected distance moduli. The results are based on a sample of 146 open clusters with known radial velocities located in the Galactic plane (b < 7degrees) within 4 kpc of the Sun. The solar Galactocentric distance R-0 is determined using two kinematic methods. The following results are obtained: A(0) = 17.0 +/- 0.9 km/s kpc, U-0 = 10.5 +/- 1.0 km/s, V-0 = 11.5 +/- 1.1 km/s, R-0 = 8.3 +/- 0.3 pc. (C) 2004 MAIK "Nauka/Interperiodica".
