摘　　要：利用北京天文台BATC巡天观测中的部分资料──20幅CCD图像，通过IRAF处理软件和底片常数法，归算得到4个河外射电源光学对应体的光学位置，参考星表为最新的CAMC星表；同时对本文结果与射电位置进行了比较。From the data of CCD multi-colour survey of Beijing-Arizona-Taipei-Connecticut (BATC), 20observations that have the radio sourees were selected. The centers of the star images were obtained with the IRAF software. Taking the latest CAMC as reference catalogue, and using the plate-constan method, the optical positions of four extragalactic radio sources 0851+202, 1228+126, 1442+101,1749 +701 were obtained. The comparison between our results and radio positions is also given in the paper.
