Optical and Infrared Flux Variability of the FSRQ 3C 454.3

摘要：

　　Based on the introduction of the flat-spectrum radio quasar 3C 454.3,the optical and infrared data are collected,and the historical light curve,color index change and time delay are analyzed according to the data.The results are as follows:(1)The light curve indicates that the targets optical activity is intense and unstable,and may have periodic components of 79.89 days and 53.26 days in the optical B-band.(2)Color index analysis shows that there are many correlations between color index and brightness.(3)The DCF method indicates that there is no significant time delay in the optical changes of the target optical and infrared bands.
