采用二维静电场模型，数值研究了湍流与非线性撕裂模的相互作用。湍流的模式的传播速度的不同的根源之间的过渡。的过渡采取的模式向根与较慢的传播，其特征在于由一个局部平坦的密度分布。对于足够大的岛的过渡减少了驱动器的撕裂模式。
The interaction between turbulence and a nonlinear tearing mode is investigated numerically using a 2D electrostatic model. Turbulence is found to cause transitions between the different roots for the propagation velocity of the mode. The transitions take the mode towards roots with slower propagation that are characterized by a locally flattened density profile. For sufficiently large islands the transition reduces the drive for the tearing mode.
