英文摘要Based on the DEMETER satellite, we found two space wave-particle coupling events during February 2010 that took place in the range of the McIlwain parameter L (1.27 similar to 1.37). There are strong spatial and temporal correlation between the particle bursts (PBs) and the electromagnetic disturbances of the coupling events. The two PBs show different energy spectrum characteristics, while the corresponding electromagnetic disturbances concentrated on different frequency ranges. In agreement with the prediction of the theory of wave-particle interaction, we conclude that the two wave-particle interactions can be probably explained as follows: one is electron-dominant precipitation with energy of 0.09 MeV similar to 0.2 MeV induced by a VLF electromagnetic wave with the frequencies of 14 kHz similar to 20 kHz, and another is proton-dominant precipitation with energies of 0.65 MeV similar to 2.85 MeV induced by a VLF electromagnetic wave with the frequency of <= 100 Hz. For the first time, these particle bursts' origins, from electrons or protons detected by the Instrument for the Detection of Particles (IDP) on board, are inferred by theoretical calculation, although the instrument has no ability to identify the particle species.
