Magnetic islands (MIs), resulting from a magnetic field reconnection, are ubiquitous structures in magnetized plasmas. In tokamak plasmas, recent researches suggested that the interaction between an MI and ambient turbulence can be important for the nonlinear MI evolution, but a lack of detailed experimental observations and analyses has prevented further understanding. Here, we provide comprehensive observations such as turbulence spreading into an MI and turbulence enhancement at the reconnection site, elucidating intricate effects of plasma turbulence on the nonlinear MI evolution.

等离子体湍流对托卡马克磁岛非线性演化的影响

磁场重新连接产生的磁岛（MIs）是磁化等离子体中的普遍结构。在托卡马克等离子体中，最近的研究表明，MI和环境湍流之间的相互作用对于非线性MI的发展可能很重要，但是缺乏详细的实验观察和分析阻碍了进一步的理解。在这里，我们提供了广泛的观察结果，例如湍流扩散到MI中，以及在重新连接位置处湍流增强，从而阐明了等离子体湍流对非线性MI演化的复杂影响。
