【摘要】：日冕波自从被发现以来，关于它是不是真正的波一直是太阳物理学界的热门话题，直到现在还没有一致的结论。2011年8月4日，太阳动力学天文台(SDO)利用193波段观测到一个日冕波，通过对这个日冕波的研究，发现日冕波在传播过程中和一些日冕结构发生了相互作用，当日冕波遇到暗条通道时，，一部分日冕波发生了反射，另一部分日冕波继续沿着原来的方向传播，当日冕波遇到活动区时，日冕波以非常快的速度穿过活动区并且形成一个新的半弧型的亮波前，通过分析我们认为这可能是日冕波在遇到该活动区时发生了折射，折射波穿过活动区后形成了这个新的半弧型的亮波前。而当日冕波和两个日冕亮结构相互作用时，发现日冕波连续发生了二次反射。从观测到的日冕波在遇到暗条通道和日冕亮结构发生了反射，在遇到活动区时发生了折射等这些现象可以推断出这里观测到的日冕波可能是真正的波动现象。
[Abstract]:The coronal wave has been a hot topic in solar physics since it was discovered. A coronal wave was observed by (SDO) in 193-band. By studying the coronal wave, it is found that the coronal wave interacts with some coronal structures during its propagation, and when the coronal wave encounters a dark stripe channel, it is found that the coronal wave interacts with some coronal structures during the propagation of the coronal wave. Some of the coronal waves are reflected, and the other part of the coronal waves continue to travel along the original direction. When the coronal waves meet the active region, the coronal waves travel through the active region at a very high speed and form a new half-arc bright front. It is considered that the coronal wave may be refracted when it encounters the active region, and the new half-arc bright wave front is formed after the refraction wave passes through the active region. When the coronal wave interacts with two bright coronal structures, it is found that the coronal wave has a continuous secondary reflection. From the phenomena that the observed coronal waves are reflected in the dark channel and the bright structure of the corona, and refraction occurs in the active region, it can be inferred that the observed coronal wave here may be a real wave phenomenon.
