我们目前的磁层多尺度观测显示大量的慢电子空穴的速度聚集在当地的最小值的双峰速度分布函数的背景离子。理论计算表明，慢电子空穴可以避免加速，否则只会在这些相同的情况下阻止它们保持缓慢。虽然慢电子空穴的起源仍然难以捉摸，但关于它们存在的条件，观测和理论之间的一致性是显著的。
We present Magnetospheric Multiscale observations showing large numbers of slow electron holes with speeds clustered near the local minimum of double-humped velocity distribution functions of background ions. Theoretical computations show that slow electron holes can avoid the acceleration that otherwise prevents their remaining slow only under these same circumstances. Although the origin of the slow electron holes is still elusive, the agreement between observation and theory about the conditions for their existence is remarkable.
