摘要
文章从有关文献中收集了 3C 3 71近 1 0 0年的光学观测数据 ,并运用Jurkevich的方法研究了它的长期光变的周期性。我们发现 ,3C 3 71在B波段观测的最大变化幅度ΔB =2 m.3 1。用Jurkevich的方法分析B波段的数据 ,得到了一个 6.
In this paper, the historic optical date (about 100 year) are compiled from the available literature for the N Galaxy 3C 371,and used to search for the periodicity by the means of Jurkvich's method. We fond that the largest amplitude variation of the N Galaxy 3C 371 was Δ=2 m.31 in the B band, Jurkevich's method indicates a 6.81 year period in the B light curve.
