斯威特-帕克电流片的形成，实际上是一个平板，研究了部分电离等离子体。离子中性阻力、双极性扩散、电子中性和电子离子碰撞产生的电阻率以及霍尔电场的影响对确定电流板的尺寸和磁重联率很重要。霍尔效应使薄板变成厚板。伴随着板状结构，霍尔效应和双极效应共同产生的面外等离子体流是一个重要的标志性结果。虽然双极效应提高了重联率，而霍尔效应降低了重联率，但由于缺乏天体物理环境中重联区附近精确物理条件的信息，其定量估计最多只能被认为是一个指针。
The formation of the Sweet–Parker current sheet, in fact a slab, is studied for a partially ionized plasma. The effects arising from the ion–neutral drag, the ambipolar diffusion, the resistivity resulting from electron–neutral and electron–ion collisions, and the Hall electric field are important for determining the dimensions of the current slab as well as the magnetic reconnection rate. It is the Hall effect that transforms the sheet into a slab. Along with the slab configuration, the out-of-plane plasma flow generated jointly by the Hall and the ambipolar effects is an important signature result. Although the ambipolar effect enhances and the Hall effect depletes the reconnection rate, its quantitative estimate may, at best, be considered only a pointer, owing to the lack of information on the precise physical conditions near the reconnection region in astrophysical settings.
