中文摘要	We examine and simulate the electron radiation belt dropout event on 9 October 1990. CRRES observations show that significant depletions of electron fluxes occurred at energies similar to 0.1- 1.0 MeV beyond 6 R-E and at energies >similar to 0.4 MeV within 6 R-E. The three- dimensional kinetic radiation belt model STEERB is used to simulate this dropout event, taking into account the magnetopause shadowing, adiabatic transport, radial diffusion, and plume and chorus wave- particle interactions. Our results show that STEERB code can basically reproduce the observed depletion of similar to 0.1-1.0 MeV electron fluxes throughout the outer radiation belt, suggesting that the competition and combination of all these physical mechanisms can well explain this electron radiation belt dropout event.
