本文是关于极光离子沉淀的。由于测量困难，与电子沉淀研究相比，这一课题很少受到重视。速度分散离子结构（VDIS）的发现激发了人们的兴趣。人们普遍认为，离子中含有有关远磁尾性质及其动力学的重要信息。作者查看了来自AUREOL-3的最新数据来研究离子沉淀剖面。他们在离子沉淀剖面中观察到一个间隙，他们认为这与VDIS有关，并且是在10r附近区域增强的交叉尾电流的标志[sub E]。
This paper is concerned with auroral ion precipitation. This subject has received little attention by comparison with electron precipitation studies because of the difficulties with measurements. The discovery of velocity dispersed ion structures (VDIS) stimulated increased interest. It has been accepted that the ions contain important information about properties in the distant magnetotail, and its dynamics. The authors look at recent data from AUREOL-3 to study the ion precipitation profiles. They observe a gap in the ion precipitation profiles, which they argue correlates with the VDIS, and is a signature of the enhanced cross tail current in the region near 10 R[sub E].
