未证认的IRAS　LRS源的光学证认和观测研究2．北天13~h─24~h部分具

Optical Identification and Observation of the Unidentified IRAS LRS Sources 2.Part of the Sources with Silicate Feature in the Region 13h<α<24h,0°<δ<66°

用北京天文台兴隆站１．２６ｍ红外望远镜对北天１３ｈ＜α＜２４ｈ，０°＜δ＜６６°，部分具有硅酸盐特征的源进行了ＪＨＫ测光观测研究，并对其中的一些特殊源进行了讨论。

Using the 1.26m infrared telescope at the Xinglong Station of Beijing Astronomical Observatory,we carried out JHK photometry for a subset of the sources with silicate feature in the region 13h<α<24h,0°<δ<66°,and present the results in this paper with a discussion on some peculiar sources.
