英文摘要	The gyroresonant interaction between electromagnetic ion cyclotron (EMIC) waves and energetic particles was studied in a multi-ion (H+, He +, and O+) plasma. The minimum resonant energy E min, resonant wave frequency ??, and pitch angle diffusion coefficient D???? were calculated at the center location of the symmetrical ring current: r 3.5RE with RE the Earth's radius. Emin is found to decrease rapidly from 10 MeV to a few keV with the increase in ?? in three bands: H+-band, He +-band and O+-band. Moreover, EMIC waves have substantial potential to scatter energetic (??100 keV) ions (mainly H+ and He+) into the loss cone and yield precipitation loss, suggesting that wave-particle interactions contribute to ring current decay.; EI; 0; 5; 539-543; 11
