摘要：

We numerically investigate the effects of ion-to-electron temperature ratio Ti/Te and temperature gradient ratioηi/ηe on resistive ballooning inodes（RBMs） under tokamak edge plasma conditions.The results show that the growth rates of the RBMs exhibit the characteristic of a quite broad poloidal wavenumber spectrum in the cold ion limit.The growth rate spectrum becomes narrower and the peak of the spectrum shifts from the short to long wavelength side with increasing Ti/Te and ηi/ηe.The electron temperature gradient has a very weak effect on the stability of RBMs.However,the ion-to-electron temperature ratio and the temperature gradient ratio have strong stabilizing effects on short-wavelength RBMs,while they have relatively weak effects on long-wavelength RBMs.
