In this paper, we have studied the influence of resonance magnetic perturbation (RMP) on the double tearing modes induced by asymmetric magnetic perturbation in a 2D geometry based on the MHD model. After studying the four cases, we have found that with RMP, no matter which rational surface the magnetic perturbation is in: (1) the width of the outer magnetic island will be greater than that of the inner magnetic island at the end of the mode evolution; (2) The influence of the RMP on the outer magnetic island is far greater than the inner magnetic island; (3) RMP will shorten the time required for the magnetic island to reach saturation.

共振磁扰对非对称磁扰诱导双撕裂模式的影响

在本文中，我们研究了共振磁扰 (RMP) 对基于 MHD 模型的二维几何中由非对称磁扰引起的双撕裂模式的影响。经过对四种情况的研究，我们发现使用RMP，无论磁扰在哪个有理面：（1）在模态末端外磁岛的宽度将大于内磁岛的宽度进化; (2) RMP对外磁岛的影响远大于内磁岛；(3) RMP 将缩短磁岛达到饱和所需的时间。
