| 摘 要： | 采用二级理论研究了在等离子体片边界层电磁不稳定性引起的波—粒输运．结果表明，束流离子被热化和各向同性化，离子最大加热率峰值与电磁不稳定性最大增长率峰值出现在大致相同的方向上．被热化和各向同性化的束流离子可能是等离子体片中心区热离子的来源．这些结果对于理解等离子体片边界层的输运过程具有重要的意义．

| Abstract: | The wave-particle transport from electromagnetic instabilities in the plasma sheet boundary layer(PSBL)are studied by using the second-order theory.The results show that the ion beams are thermalized and isotropized,and the peak heating rates of ions occur near the direction corresponding to the peak growth of the electromagnetic waves.The thermalized and isotropized beam ions may be the source of hot ions in the central plasma sheet.These results are very helpful to understand the transport processes in the plasma sheet boundary layer. |
