中文摘要：

针对Blazar3C454．3的长期偏振变化现象，采用PowerSpectrum方法分析其变化周期，结果显示其变化周期是τ1=17．9a，τ2=6．9a和τ3=3．9a．利用bin=10d得到各个分段的谱指数和平均偏振度，发现两者之间存在一定的相关性．

英文摘要：

Based on the long-term polarized variability of Blazar 3C4543, the authors use the power spectrum to analyze its periodicity,and obtain that the periodicities are τ1 =17.9 year,τ2 =6.9 year and τ3 = 3.9 year. Using bin= 10 days, the author obtain the spectral index and averaged polarization, and get weak correlation between them.
