摘要
本文从几个方面考察了ＢＬＬａｃ天体和ＯＶＶ类星体的完备样品的性质：谱性质，ａｏｘ─ａｒｏ，Ｂ─Ｖ──Ｕ─Ｂ，视星等──红移，光度──红移，超光速──射电功率等．这些性质都支持两类天体的同一性．
Discussed in this paper are the properties of complete samples of BL Lac objects and OVV quasers, such as spectrum, infective indices, B─V──U─B, magnitude─redshift, luminosi ty─luminosity, superluminal motion─radio power, etc., which suggest that the two kingds of ob jects belong to a single category originally.
