摘　　要：对类星体进行多波段的观测和研究，是了解类星体本质的一个重要途径．LBQS类星体是目前公认较为完备的一个光学选类星体样本，利用此样本与最新的485GHz全天射电源表进行了交叉证认，共找到了34个类星体的对应射电源．计算证明，这34个类星体都是射电噪的类星体．所得研究结果表明，射电噪类星体的射电光度与光学光度之间存在线性相关性．It is important to understand the nature of quasars from their multi-wave information. Based on an ideal sample of optically selected quasars provided by the LBQS, we carried out an identification with the latest whole-sky survey catalog of 4.85GHz radio sources. As a result, 34 quasars were found to have radio counterparts and proved to be radio-loud quasars. We studied the relation between their radio and optical luminosities and found a nearly linear correlation.
