本文通过数值求解平板模型中本征模方程,研究了安全因子q极值点附近的低频漂移波稳定性问题。数值计算结果表明,剪切随磁面的变化可以导致在q的极值点附近产生不稳定的漂移波模式。
In this paper, we study the eigenmode equation of the slab model numerically and study the stability of the low-frequency drift wave near the extremum of the safety factor q. The numerical results show that the change of shear with the magnetic surface can lead to the unstable drift wave mode near the extreme point of q.
