摘　　要：本文用佘山４０厘米折射望远镜拍摄的历元间隔约为３０年的９张底片上共１７次露光观测，以ＰＰＭ星表作为初始参考星表，用中心重迭法进行叠代归算，得到了射电源０３１６十４１３附近的２８颗星的高精度位置和自行，其中６颗为依巴谷星，这些依巴谷星的赤经自行和赤纬自行内部误差的平均值分别为■年和■年．In this paper, using the PPM catalogue as a preliminary reference catalogue, we have reduced 17 exposures on 9 plates taken with the 40cm refractor at Z■-S■ Station of Shanghai Astronomical Observatory in about 30 years. By means of the central overlapping technique and the iterative process, high-precision positions and proper motions of 28 PPM stars, including 6 Hipparcos stars in the region of radio source 0316+413 are obtained. The mean values of the internal standard errors of proper motions in right ascension and declination for the 6 Hipparcos stars are and respectively.
