研究了两个典型高偏振类星体(0836+710和2251+158)在三个厘米波段(4.8GHz,8GHz和14.5GHz)的流量密度与偏振度关系.线性相关分析结果表明偏振度与流量密度强负相关.这些强负相关性不能用聚束效应解释,而能用喷流中激波的传播来解释.

The correlations between flux density and polarization degree at three centimeter wavebands (4.8,8 and 14. 5GHz) of two typical high polarization quasars (0836 +710 and 2251 + 158) are studied. The results of linear correlation analysis indicate that the polarization degrees are strongly anti-correlated with the flux densities. It is suggested that not beaming effect but shock wave propagation in jet account for these strong flux-polarization anticorrelations.
