在最近的联合释放和辐射效应卫星（CRRES）任务中，在磁层和电离层发生了一系列化学释放，以研究大范围的等离子体过程。实验旨在研究(1)受激电子和离子沉淀，(2)磁尾中的离子传输，(3)临界电离速度（CIV），(4)场线追踪和平行加速，(5)反磁腔的形成和坍缩，以及(6)等离子体的不稳定性。卫星轨道是高度椭圆的，远地点为33 600公里，近地点为350公里。高度范围允许背景磁场强度和注入速度的变化。释放物质包括钡、锂、锶、钙和铕。船上CRRES和地面光学仪器的现场诊断记录了化学物质释放的影响。CRRES实验要么(1)验证了理论预测，(2)显示了新的、意想不到的影响，或者(3)预测了…
During the recent Combined Release and Radiation Effects Satellite (CRRES) mission, a series of chemical releases occurred in the magnetosphere and ionosphere to study a wide range of plasma processes. The experiments were designed to investigate (1) stimulated electron and ion precipitation, (2) ion transport in the magnetotail, (3) critical ionization velocity (CIV), (4) field line tracing and parallel acceleration, (5) diamagnetic cavity formation and collapse, and (6) plasma instabilities. The satellite orbit was highly elliptical having an apogee of 33 600 km and a perigee of 350 km. The range of altitudes permitted variations in background magnetic field strength and injection velocity. The release materials included barium, lithium, strontium, calcium, and europium. In situ diagnostics on board CRRES and ground‐based optical instruments recorded the effects of the chemical releases. The CRRES experiments either (1) verified theoretical predictions, (2) showed new, unanticipated effects, or (3) pres...
