估计星际空间中航天器周围的光电子鞘和相关电场的范围对于解释探测器测量结果是重要的。此外，该理论还与预测月球等天体周围的鞘层参数有关。本文对真空中的光电子鞘层作了一般性的处理，给出了典型的鞘层剖面，并讨论了稀薄环境等离子体的影响。最后，试图归因于数量级的物理参数的光电子鞘。
Estimating the extent of the photoelectron sheath and associated electric field around a spacecraft in interplanetary space is important for the interpretation of probe measurements. In addition the theory is relevant to predicting the sheath parameters around bodies such as the moon. In the present study a general treatment of the photoelectron sheath in a vacuum is undertaken, typical sheath profiles are given, and the effects of a tenuous ambient plasma are also discussed. Finally an attempt is made to ascribe orders of magnitude to the physical parameters of the photoelectron sheath.
