日珥振荡现象早在20世纪就被发现,是太阳上较常见的现象之一。由这一现象而发展出的珥震学方法,有助于得到日珥本身所处的磁结构及周围磁场环境的基本信息,具有较为重要的研究价值。回顾了日珥振荡的发现和研究的历史过程,综述了日珥振荡的一些基本性质及国内外对日珥振荡及珥震学方法的部分研究成果,并指出这一领域一些尚未得到解决的问题。
According to velocity amplitude,prominence oscillations can be classified into two groups:large amplitude oscillations(>20km·s?1)and small amplitude ones(1~3km·s?1).Large amplitude oscillations are usually initiated by interactions between prominences and coronal waves that are generated by distant flares.Sometimes,nearby energetic events,such as jets,sub-flares or magnetic reconnection,can also trigger such oscillations.
