论文摘要
太阳丝是太阳盘上的深色结构，有细长的脊柱和几个倒钩从脊柱延伸。出现在太阳肢上方时，灯丝称为突出，几英尺延伸到太阳表面。人们普遍认为，细丝倒钩只是从脊柱向下转向太阳表面的突出脚。但是，最近注意到可能存在另一种动态类型的倒钩，这是由于丝线螺纹纵向振荡所致。如果是这种情况，动态倒钩不会向下延伸至太阳表面。随着2011年6月5日从{\ it太阳动力学天文台}和{\ it立体声}卫星的细丝倒钩的正交观察结果，我们确认丝线倒钩是由于细丝线纵向振荡所致。从侧面看，细丝倒钩看起来像沿突出的脊柱的附录，并且不会延伸到太阳表面作为脚。
Solar filaments are dark structures on the solar disk, with an elongated spine and several barbs extending out from the spine. When appearing above the solar limb, a filament is called a prominence, with several feet extending down to the solar surface. It was generally thought that filament barbs are simply the prominence feet veering away from the spine and down to the solar surface. However, it was recently noticed that there might be another dynamic type of barbs, which were proposed to be due to filament thread longitudinal oscillation. If this is the case, the dynamic barbs would not extend down to the solar surface. With the quadrature observations of a filament barb on 2011 June 5 from the {\it Solar Dynamics Observatory} and the {\it STEREO} satellites, we confirm that the filament barb is due to filament thread longitudinal oscillations. Viewed from the side, the filament barb looks like an appendix along the spine of the prominence, and does not extend down to the solar surface as a foot.
