摘　　要：利用佘山40cm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星表中28颗星构成初始参考星表，按中心重叠法进行归算，得到了射电源0316＋413光学对应体的高精度位置和自行，求得该源的赤经和赤纬标准误差分别为σα=±0s．0038和σδ＝±0″．054，　赤经自行和赤纬自行标准误差分别为σμα＝±0s.000107／yr和σμδ＝0.″．00228／yr。In this paper, using 28 stars in the PPM catalogue as a preliminary reference catalogue,we reduced 17 exposures on 9 plates taken with 40cm refractor at Sheshan(Zo - Se) in 30 years. By means of central overlapping technique, accurate positions and proper motions of the radio source 0316+413 are obtained- The internal standard errors of the positions of this radio source in right ascension and declination are σα= ±0s. 0038 and σδ= ±0″. 054, respectively. The internal standard errors of proper motions of right ascension and declination of this radio source are σμα. = ± 0s. 0000107/yr and σμδ = ± 0″. 00228/yr, respectively. We also compared this work results with other auther's optical and radio catalogue , respectively.
