本文提出了一类具有正极性的二维太阳静止辐射模型。这代表了基彭汉-施吕特模型的扩展，其中日珥结构平滑地匹配到恒定α场的外部非势日冕解。使用典型的日珥值的模型也符合日冕条件。结果表明，磁场沿着向分量影响着日珥的内部结构。一个简单的扩展的基本模型表示作为一种手段，采取较低的边界的突出和消除寄生极性的光球。
A class of 2-D models of solar quiescent prominences, with normal polarity, is presented. These represent an extension to the Kippenhahn-Schlüter model for which the prominence configuration matches smoothly onto an external non-potential coronal solution of a constant α field. Using typical prominence values a model is constructed which also matches the coronal conditions. It is found that the magnetic field component along the prominence influences the internal structure of the prominence. A simple extension to the basic models is indicated as a means of taking a lower boundary of the prominence and eliminating parasitic polarities in the photosphere.
