| 英文摘要 | Using the database of the University of Michigan Radio Astronomy Observatory (UMRAO) at three radio frequencies (4.8, 8 and 14.5 GHz), we determined the short-term variability timescales for 166 radio sources. The timescales are 0.15d (2007+777) to 176.17 d (0528-250) with an average timescale of Delta t(obs) = 17.1 +/- 16.5 d for the whole sample. The timescales are used to calculate the brightness temperatures, T(B). The value of log T(B) is in the range of log T(B) = 10.47 to 19.06 K. In addition, we also estimated the boosting factor for the sources. The correlation between the polarization and the Doppler factor is also discussed. |
