摘要：
Non-linear development of double tearing modes induced by electron viscosity isnumerically simulated.MHD flow layers are demonstrated to merge in the development of themodes.The sheared flows are shown to lie just at the boundaries of the magnetic islands,and tohave suffcient levels required for internal transport barrier(ITB)formation.Possible correlationbetween the layer formation and triggering of experimentally observed ITBs,preferentially formedin proximities of rational flux surfaces of low safety factors,is discussed.
