摘　　要：从相关时间以及色散关系分析入手 ,研究磁约束等离子体中湍流扰动的纵向传播性质 ,从不同途径来确定扰动的传播速度。其结果与电子流体速度具有一致性。从而表明 ,时间相关因数与色散关系这两种分析方法 。The time correlation and dispersion relation analysis of toroidal propagation of the turbulent perturbation in magnetically confined plasma were carried out to estimate the phase velocity of the perturbation. The results show that the phase velocities obtained by different methods are in good agreement with the electron fluid velocity, and indicate that the time correlation and dispersion relation analysis are effectively equivalent methods in the research of the propagation velocity of the turbulent fluctuation.
