摘　　要：The influences of the temperature gradient and toroidal effects on drift-tearing modes have been studied using the Gyrokinetic Toroidal code.After the thermal force term is introduced into the parallel electron force balance equation,the equilibrium temperature gradient can cause a significant increase in the growth rate of the drift-tearing mode and a broadening of the mode structure.The simulation results show that the toroidal effects increase the growth rate of the drift-tearing mode,and the contours of the perturbation field“squeeze”toward the stronger field side in the poloidal section.Finally,the hybrid model for fluid electrons and kinetic ions has been studied briefly,and the dispersion relation of the drift-tearing mode under the influence of ion finite Larmor radius effects is obtained.Compared with the dispersion relation under the fluid model,a stabilizing effect of the ion finite Larmor radius is observed.
