回顾了离子相空间涡旋的性质，特别关注它们在载流等离子体中小振幅双层形成中的作用。在一维分析中，许多这样的双层简单地加起来就会产生很大的电压降。进行了实验室实验，以研究三维离子相空间涡旋的特性。与问题的一维数值模拟的类似结果相比，它们的寿命显着缩短。
The properties of ion phase-space vortices are reviewed with particular attention to their role in the formation of small amplitude double layers in current-carrying plasmas. In a one-dimensional analysis, many such double layers simply add up to produce a large voltage drop. A laboratory experiment is carried out in order to investigate the properties of ion phase-space vortices in three dimensions. Their lifetime is significantly reduced as compared with similar results from one-dimensional numerical simulations of the problem.
