The hysteresis relation between turbulence and temperature modulation during the heat pulse propagation into a magnetic island is studied for the first time in toroidal plasmas. Lissajous curves of the density fluctuation (n[over ˜]/n) and the electron temperature (T_{e}) modulation show that the (n[over ˜]/n) propagation is faster than the heat pulse propagation near the O point of the magnetic island. This faster n[over ˜]/n propagation is experimental evidence of the turbulence spreading from the X point to the O point of the magnetic island.
首次在环向等离子体中研究了热脉冲传播进入磁岛期间湍流与温度调制之间的滞后关系。密度涨落（n[over ˜]/n）和电子温度（T_e）调制的 Lissajous 曲线表明，在磁岛的 O 点附近，n[over ˜]/n 的传播速度比热脉冲传播速度快。这种更快的 n[over ˜]/n 传播是湍流从磁岛的 X 点扩散到 O 点的实验证据。
