摘　　要：The“softening”process of the first kind of dumbbell domains(IDs)with the increase of temperature was experimentally revealed as follows:IDs first convert to ordinary hard bubbles(OHBs)through a partial loss of the vertical Bloch lines(VBLs)in their walls and then these OHBs convert to soft(normal)bubbles(SBs)through a further loss of VBLs.As a result,the critical temperature for the break down of VBL chains of IDs is apparently higher than OHBs.
