The ratio RT of the jet to the unbeamed luminosities for superluminal radio sources

Relativistic beaming model has been successfully used to explain the observational properties in active galactic nuclei. In this model the emissions are composed of two components, i.e. the boosted and the isotropic emissions. But how much is from each part is unknown. It has been assumed that the luminosity in the jet is proportional to the unbeamed in the comoving frame. However, the value of this ratio is not easy to determine. In this paper, we use the beaming model and the radio sources with superluminal motions to estimate the ratio, R_T, for each source. We find R_T= 0.044±0.02, which is consistent with that found by Orr and Browne.     

Aharonov-Bohm效应的验证

验证Ａ－Ｂ效应，是现代物理学中一个重大问题．它使量子理论受到严峻的考验，并使电磁场理论引起变革和发展．自从１９６０年对首次的实验结果有所争议以来，经过二十多年的探索，电磁矢势的Ａ－Ｂ效应终于获得确证．本文着重介绍这一验证的思想、方法和结果．
