[1]我们研究了土星内部磁层(5100 EV)中两个不同电子成分的来源，它们可能是土星的中间或外部磁层，可能是通过交换式注入调节的径向扩散传输到内部磁层的。在L∼6内，超热电子遭受严重损失，超热电子穿透中性云的距离与能量有关，超热等离子体的最冷部分穿透到最低的L壳层。这可以通过交换过程中依赖能量的径向传输和/或通过行星损失锥的损失来发生。
[1] We investigate the sources of two different electron components in Saturn's inner magnetosphere (5 100 eV) is Saturn's middle or outer magnetosphere, perhaps transported to the inner magnetosphere by radial diffusion regulated by interchange-like injections. Hot electrons undergo heavy losses inside L ∼ 6 and the distance to which the hot electron component penetrates into the neutral cloud is energy-dependent, with the coolest fraction of the hot plasma penetrating to the lowest L-shells. This can arise through energy-dependent radial transport during the interchange process and/or loss through the planetary loss cone.
