| 摘 要： | 本文导出了螺旋结构日珥内螺度的表达式，并利用观测资料计算内螺度，结果表明，内螺度的大小与日珥的稳定性有关；空静日卫内螺度较小，爆发日珥的内螺度较大；在日珥从宁－爆发－匀速上升到演化过程中，螺度将不断积累－释放－转移到日冕空间

| Abstract: | The magnetic inner helicity of the prominence with belieal structure is inferredin this paper. Using the observational data, the value of inner helicity is calculated.It is shown that. (1) the scale of the inner helicity is related to the stability of thebelieal prominence; (2) the quiescent prominence has smaller inner helicity, whilethe eruptive prominence has larger helicity; (3) in the whole evolutional processof the prominence (e.g. quiescent-eruptive- stable ), t he helicity increase s firstly andthen it is transferred to the high corona. |
