我们研究了3C 279的pc尺度喷流是由正常等离子体还是正负电子等离子体主导的。通过对1983 ~ 1990年甚长基线干涉测量数据的分析，利用同步辐射自吸收理论，导出了本征电子数密度的下限。将下限与从动力学光度推导出的电子密度的另一个独立约束进行比较，我们发现核心和组件C3和C4可能由电子-正电子等离子体主导。
We have investigated whether a pc-scale jet of 3C 279 is dominated by a normal plasma or an electronpositron plasma. By analyzing Very Long Baseline Interferometry data between 1983 and 1990, and utilizing the theory of synchrotron self-absorption, we have derived the lower limits for the proper electron number density. Comparing the lower limit with another independent constraint for the electron density that is deduced from the kinetic luminosity, we find that the core and components C3 and C4 are likely dominated by an electron-positron plasma.
