收集了一个具有光学和射电偏振的blazar样本,讨论了光学和射电偏振与喷流参数之间的关系.第一,蝎虎天体(BL Lac object,BL Lac)的偏振高于平谱射电源(Flat Spectrum Radio Quasar,FSRQ)的偏振,核主导系数R和比率f都正比于本征射电和光学偏振;第二,基于该样本,可得喷流是球型的;第三,BL Lac和FSRQ具有相似的本征偏振与喷流参量(log R和f)的关系.“,”Radio and optical polarizations are collected for a blazar sample.The relationships between polarization and jet parameters are investigated.The analysis results indicate that (1) polarization in BL Lac is higher than in FSRQs,and the core dominance parameter R and the ratio f are both positively correlated with intrinsic radio and optical polarizations;(2) the jet type is spherical;(3) BL Lacs and FSRQs have a similar correlation between the intrinsic polarization and jet parameters (log R and f).
