| 英文摘要 | In quasi-linear approximation, we study wave-electron resonant interaction near the geosynchronous orbit. a part of lower energy electrons decrease while the higher ones increase after distribution function of electrons evolve with time via momentum diffusion, which suggest that "seed electrons" are accelerated effectively by the whistler turbulence. the larger the energy of whistler turbulence is, the higher the acceleration efficiency is. in addition, the lower the frequency of the whistler, the higher the energy of resonant electrons; and the wider the frequency range of the whistler, the wider the energy range of resonant electrons, and the more the accelerated electrons. electron acceleration by the whistler turbulence can markedly increase the number of relativistic electrons within about 30 hours, which is consistent with the observation of relativistic electron flux enhancements during most magnetic storms. |
