| 摘 要： | 利用具有螺旋结构的宁静日珥观测资料,基于:(1)日珥内部的磁场位形具有无力性质;(2)日珥整体电流性质可用Kippenhahn-Schlüter模型描述;从理论上探讨了这些日珥的电流特性。并将所得结果与Kuperus-Raadu日珥模型进行了比较,结果表明:(i)日珥内部的磁场和电流确实具有无力性质;(ii)不考虑虚镜电流的Kippenhahn-Schlüter模型可能是描述宁静日珥电流特性的较好模型;(iii)可能存在两类导致日珥爆发的物理原因。

| Abstract: | Using observed data of quiescent prominences with helical structure,the current properties of the quiescent prominences are studied with (i) the magnetic field inside prominences is force-free,(ii) the basic characteristics of prominence current is described by Kippenhahn-Schlu-ter model.The results are compared with Kuperus-Raadu model.They indicate that (1) the magnetic field and current inside prominences must be force-free;(2) Kippenhahn-Schluter model without mirror current may be a better model of quiescent prominebces;(3) there are two kinds of physical reasons causing the eruption of prominences. |
