本文对Ferraro - Rosenbluth冷等离子体鞘层模型进行了精确的相对论处理，并与Sestero先前给出的非相对论解进行了比较。发现，尽管离子流和电子流在空间上是分离的，但由Sestero得到的反常解，即离子在电子之前返回的事实，在相对论处理中仍然存在。与塞斯特罗解一样，我们发现鞘层中的全部电荷一般不为零。给出了与太阳风速度相当的情况下的数值说明。
The exact relativistic treatment is given of the Ferraro‐Rosenbluth cold plasma sheath model, and is compared with the nonrelativistic solution given previously by Sestero. It is found that the anomalous solution obtained by Sestero, namely, the fact that the ions turn back before the electrons, persists in the relativistic treatment although the ion stream and electron stream are separated in space. As in the Sestero solution it is found that the over‐all charge in the sheath is not in general zero. Numerical illustrations are given for the case when the velocities are comparable with the velocities encountered in the solar wind.
