摘要
从大量文献资料中，收集了类星体3C345光学B波段的有效观测数据点共1642个，获得了从1896年至1993年的历史光变曲线．用Jurkevich方法计算分析3C345的光变周期，结果表明3C345的长光变周期为10．1±0．8年（或21．8±1．5年），预期2002年1月应该为再次爆发期．
All the data for the B band of the quasar 3C345, presented in twenty-one publications and dating back to 1896, have been compiled to be a light curve.Altogether 1642 values are available. Using Jurkevich's method, we have found a period of 10.1±0.8 years (or 21.8±1.5 years) for the outbursts in 3C345. Based on this period, we can predict that the next outburst should be at its maximum around January 2002.
