本文对含有低能等离子体的孤立快速旋转磁层的结构作了解析处理。等离子体被限制在赤道平面上的薄片中。就整个磁层而言，它的影响相当于方位电流片的影响。当假设电流分布具有某种形式时，可以用简单函数来描述完整的解。结果表明，中性点最终出现在磁场配置，表明磁层是无法容纳额外的等离子体与假设的分布。
The structure of an isolated rapidly rotating magnetosphere containing low-energy plasma is treated analytically. The plasma is confined to a thin sheet lying in the equatorial plane. Its effects as far as the magnetosphere as a whole is concerned are equivalent to those of an azimuthal current sheet. When the current distribution is assumed to have a certain form, it is possible to describe the complete solution in terms of simple functions. It is shown that neutral points eventually appear in the magnetic field configuration, indicating that the magnetosphere is unable to contain additional plasma with the assumed distribution.
