已知类星体3C 279会出现光学偏振角旋转的现象。我们提出了新的，良好的采样光学偏振数据3C 279，并介绍了一种方法来区分随机和确定性的电矢量位置角（EVPA）的变化。我们观察了EVPA在两个方向上不同幅度的旋转，发现EVPA的变化表现出随机和确定性的两种情况下的特点。我们的分析表明，EVPA的变化很可能是由一个随机过程中的低亮度状态的射流和燃烧状态的确定性过程。
Quasar 3C 279 is known to exhibit episodes of optical polarization angle rotation. We present new, well-sampled optical polarization data for 3C 279 and introduce a method to distinguish between random and deterministic electric vector position angle (EVPA) variations. We observe EVPA rotations in both directions with different amplitudes and find that the EVPA variation shows characteristics of both random and determin- istic cases. Our analysis indicates that the EVPA variation is likely dominated by a random process in the low brightness state of the jet and by a deterministic process in the flaring state.
