| 摘 要： | 基于密歇根大学射电天文台数据库(University of Michigan Radio Observatory Datebase—UMRAO),分析了3C345在射电波段的偏振性质.利用功率谱方法得到其在4.8、8和14.5 GHz处的长期偏振变化的周期分别为:11.1±1.7、11.8±1.5和10.9±1.6 yr.

| Abstract: | Based on the database of University of Michigan Radio Observatory(UMRAO),We analyze the long-term polarized variability of 3C345.Using the method of the power spectrum,we obtain the periodicities of the polarized variability at three bands,which are P4.8GHz=11.1±1.7 year,P8GHz=11.8±1.5 year,P14.5GHz=10.9±1.6 year. |
