Stratification due to ion-ion friction in a magnetized multiple-ion species plasma is shown to be accompanied by a heat pump effect, transferring heat from one ion species to another as well as from one region of space to another. The heat pump is produced via identified heating mechanisms associated with charge incompressibility and the Ettingshausen effect. Besides their academic interest, these effects may have useful applications to plasma technologies that involve rotation or compression.

通过碰撞磁化多离子等离子体中的电荷不可压缩来进行热泵。

磁化的多离子物种等离子体中由于离子离子摩擦而引起的分层显示出伴有热泵效应，将热量从一种离子物种传递到另一种离子，以及从空间的一个区域传递到另一个。通过识别出的与电荷不可压缩性和埃廷斯豪森效应相关的加热机制来生产热泵。除了其学术兴趣外，这些效应还可能对涉及旋转或压缩的等离子技术产生有用的应用。
