论文摘要
最近观察到4 = 1的连续地层；在我们的3D电阻性MHD模拟中，在低Z杂质穿透过程中，在低量杂质穿透过程中，在低量杂质穿透过程中2 = 1模式的2 = 1磁岛以及随后的2 = 1模式制动。杂质辐射引起的增强的平行电流扰动主要有助于撕裂模式的生长，而2 = 1岛旋转主要受到高N模式影响的杂质积累的抑制。
Recent observations of the successive formations of the 4=1; 3=1, and 2=1 magnetic islands as well as the subsequent braking of the 2=1 mode during a low-Z impurity penetration process in EAST experiments are well reproduced in our 3D resistive MHD simulations. The enhanced parallel current perturbation induced by impurity radiation predominately contributes to the tearing mode growth, and the 2=1 island rotation is mainly damped by the impurity accumulation as results of the influence from high n modes.
