摘要: Tokamak plasmas with highly elongated cross sections are subject to a vertical displacement event (VDE). The nonlinear magnetohydrodynamic (MHD) evolutions of tokamak during the VDE simulated by three-dimensional MHD code as combination N = 0 and 1 components. evolution is strongly affected relative amplitude modes.
