您要查找的是不是：
- When the jet is close to the line of the sight,a BL Lac object is in the high state and vice versa. 高态是喷流方向与观测者视线夹角较小的表现，而低态则是夹角较大的表现。
- In a similar way, low-power radio galaxies are a plausible parent population for BL Lac objects. 费米加速在电波喧噪活跃星系中似乎是有效的粒子加速过程。
- It is suggested that the orientation of the relativistic jet of a BL Lac object changes with the time,and thus cause the variability on long timescale. 我们提出活动星系核的相对论性喷流方向会改变，从而导致长期光变；
- It is found that the BL Lac objects in our sample show stronger activity with smaller flares and flickers in high state than that in low state. 当然太阳活动现象的复杂性不可能用简单的对应关系来说明，而且对速度场螺度的了解还非常肤浅，进一步的深入研究显得非常必要。
