人们普遍认为,VLBI源的超光速结是沿相对论喷流传播的激波。到目前为止,人们只用非常简单的准一维模型来研究这一现象。相对论流体动力学数值方法的最新进展(Falle&Komissarov,1995)使得对这种流动进行更真实的模拟成为可能。
The superluminal knots of VLBI-sources are widely believed to be shocks travelling along relativistic jets. So far only very simple quasi-one dimensional models have been used to study this phenomenon. Recent progress in numerical methods for relativistic fluid dynamics (Falle & Komissarov 1995) make it possible to carry out much more realistic simulations of such flows.
