摘      要：The behavior of multiple modes before and during minor disruption with the external resonant magnetic perturbations(RMPs)has been studied on a J-TEXT *** main component of RMPs is m/n=2/1,where m and n are the numbers of the poloidal and toroidal modes,*** the mode-locking caused by RMPs,it is found that before a minor or a major disruption(if there is no minor disruption),strong oscillations in both electron temperature and density occur if the edge safety factor q_(a)*** analysis shows that the oscillations are caused by the m/n=3/1 *** addition,using the ECE,Mirnov coils and 2D electron cyclotron emission imaging diagnostic systems,it is found that a thermal collapse occurs on the inner side of the 2/1magnetic island during the minor disruption,and before the collapse,a 3/2 island increases,after the collapse,the 3/2 island may ***,the study also shows that these 3/1,2/1 and 3/2modes play roles in the thermal collapse of disruptions.
