视超光速源的统计分析

本文收集了视超光速源样本的有关观测数据，在同步加速自康普顿散射机制下导出了各源的多普勒因子，再利用视超光速源的相对论射束模型计算样本源的有关物理量，如射电光度和亮温度，并与它们的观测值作直接的比较，得到较好的相关结果。这些结果支持了活动星系核中具有相对论射束运动的假设。同时我们比较了样本源的射电、光学、Ｘ射线的发现它们之间有一定的相关性，说明在不同波段上的辐射机制可能存在某种联系。

STATISTIC ANALYSIS OF A SAMPLE OF SUPERLUMINAL SOURCES

We collected the relevent observation data of a sample of superluminal sources and esfimated the Doppler boosting factors according to the Synchrotron Self-Compton Mechanism. The physical parameters, such as the radio luminosities and brightness temperatures are calculated with the relativistic beaming model, and compared with the observation data. Good correlations between the model predicated values and observed values are found showing evidence in support of the relativistic beaming model.By comparing the radio luminosities with the optical and X-ray ones, we also found that some correlations exist among them, which indicates some relationships of radiation mechanisms at various wavelengths.
