论文摘要
电子的一阶费米加速度需要将电子注射到一个轻度的相对论能量范围内。但是，在理论和观察中，注射机理仍然是一个难题。我们提供了一种直接证据，证明了一种新型的随机休克漂移加速度理论，用于在地球弓形冲击中通过磁层多尺度（MMS）观察获得的注射。理论模型可以解释电子加速度在高速天体物理减震器下对中等相对论的能量，这可以为长期存在的电子注入提供解决方案。
The first-order Fermi acceleration of electrons requires an injection of electrons into a mildly relativistic energy range. However, the mechanism of injection has remained a puzzle both in theory and observation. We present direct evidence for a novel stochastic shock drift acceleration theory for the injection obtained with Magnetospheric Multiscale (MMS) observations at Earth's bow shock. The theoretical model can explain electron acceleration to mildly relativistic energies at high-speed astrophysical shocks, which may provide a solution to the long-standing issue of electron injection.
