摘　　要：经典和近些年的深度Blazar巡天都表明Radio-X-ray谱指数rαx与同步辐射峰频νpeak有很好的反相关性,但后者却显示出对给定的νpeak,rαx的散射很大,不能由νpeak来导出αrx,这个差异可能源自巡天策略.Both the classic- and the resent-deeper-blazar surveys have presented an anti-correlation for αrx versus vpeak, but the latter exhibits such a broad scatter trend in vpeak for any given value of αrx that it is impossible to derive an from vpeak. The reason behind this may originate from their individual searching strategies.
