在过去五年中，利用AMPTE/IRM卫星的等离子体测量进行的统计研究使我们更好地了解了大约10RE至20RE之间近地等离子体片的结构和动力学。最值得注意的新发现是：(1)平静期尾部等离子体的绝热非等熵行为；(2)亚暴期间离子和电子的强烈非绝热加热以及离子和电子温度与Ti/Ti∼7的强耦合；(3)携带大部分尾部等离子体输运的高速流动爆发。此外，很明显，受亚暴活动影响最大的是中央等离子体片，而不是等离子体片边界层。
During the last five years, statistical studies using plasma measurements made by the AMPTE/IRM satellite have lead to a better understanding of the structure and dynamics of the near-Earth plasma sheet between about 10 and 20RE. The most notable new findings are: (1) the adiabatic non-isentropic behavior of the tail plasma during quiet times; (2) the strong non-adiabatic heating of ions and electrons during substorms and the strong coupling of the ion and electron temperature withTi/Ti∼7; and (3) the high-speed flow bursts which carry most of the tail plasma transport. Moreover, it became clear that it is the central plasma sheet, and not the plasma sheet boundary layer, which is most affected by substorm activity.
