摘    要:本文从视超光速源样品出发,对核主导系数与成束指标之间的关系,流量密度与红移之间的关系作了一定的研究。研究结果表明:核主导系数不仅是一个方向指示系数同时也是一个成束指示系数。并且核主导系数与亮温度均可作为成束指示系数;射电辐射被大大地放大了,而X射线辐射的放大效应却很小。

关 键 词:视超光速现象 亮温度 核主导系数 喷流 成束模型 河外射电源 射电辐射

Abstract:Starting form the samples of superluminal objects this paper studies the relations between core-dominance parameter(R) and other indicators of beaming model, as well as the relations between flux density and redshift. Results show that R is not only an orientation of jets, but also an indicator of beaming. R and brightness temperature (T ob) are both indicators of beaming. The radio emissions are largely enhanced by Doppler effect while X-ray emissions are hardly enhanced.
Keywords:super luminal motion  brightness temperature  core-dominance parameter  jet
