本文计算了浸没在等离子体中的光电发射板附近的电势分布，发现存在两种稳态电势分布。在一个中，电势从其板值单调地减小到零，而在另一个中，电势从其板值减小到（负的）最小值，然后缓慢地增加到零。这第二个“过冲”的潜力似乎是稳定的。这种过冲效应预计将在行星间等离子体中对卫星周围的鞘层起重要作用。
We calculate the potential distribution in the neighborhood of a photo-emitting plate immersed in a plasma, and we find that two steady state potential distributions can exist. In one the potential decreases from its plate value to zero monotonically, and in the other it decreases from its plate value to a (negative) minimum and then increases slowly to zero. This second ‘over-shoot’ potential appears to be the stable one. Such over-shoot effects are expected to play an important role for sheaths around satellites in the interplanetary plasma.
