| 摘 要： | 为了深入研究密云射电源表分类样本的性质，作为系列工作的第一部分，选出了一个２３２～４８５０ＭＨｚ平谱源样本．１９９８年５月２９至３１日，利用北京天文台２．１６米望远镜和ＯＭＲ摄谱仪，对其中１８个目标进行了观测及光谱认证．结果共证认出１５个ＡＧＮ，其中３个信噪比不小于８的ＢＬＬａｃ天体和５个类星体（最大红移为２．５１９±０．００３）是新发现的．

| Abstract: | To study special radio sources of the Miyun Survey, 18 flat spectrum sources selected from 232 4850 MHz catalogs were followed up by optical identification as the first part of a series of research programs. Having been identification with the 2.16 m telescope at Beijing Astronomical Observatory in May, 1998, 15 AGNs were found in which three BL Lac objects with no less than 8 of signal to noise ratios, MYC1557 566, MYC1615 412, MYC1902 556, and five Quasars, MYC1415 385, MYC1615 365, MYC1722 527, MYC1825 345, MYC2207 357 are newly discovered. |
