| 摘 要： | 从SMARTS数据库中，收集了3C454．3的红外J波段和K波段的光变数据，并运用结构函数法和离散相关函数方法对其光变曲线进行分析，发现3C454．3在J波段和K波段可能存在192d的周期性光变，该周期很可能是由双黑洞系统中轨道驱动的螺旋喷流引起的。还发现3C454．3在红外J波段和K波段的辐射变化具有显著的相关性。

| Abstract: | Based on the database of SMARTS, we collected the emission data of 3C 454. 3 at in- flared J and K waveloand. Using the structure function method and the discrete correlation func- tion （DCF） method, we have analyzed the light curves of 3C 454. 3 and found there a period P =192 days in the light curves of infrared waveband that is most likely caused by the helical mo- tion of the jet, and also found there exists significant correlations between the J and K wave- band. |
