【摘要】 <正>The behavior of the axial group speeds of trapped sausage modes plays an important role in determining impulsively generated wave trains,which have often been invoked to account for quasi-periodic signals with quasi-periods of the order of seconds in a considerable number of coronal structures.We conduct a comprehensive eigenmode analysis,更多还原
