The impact of velocity shear on the localized solutions of Rayleigh–Taylor (RT) and resistive drift wave (DW) instabilities has been investigated. Slab geometry is used, and the plasma density gradient is assumed to have a finite spatial structure. It demonstrates that the velocity shear has quite different effects on these instabilities: while it stabilizes RT instability and causes tilting of the eddies of equipotential contour, it has a very mild impact on the resistive DW instability and simply shifts the eddies with no tilting.

流量剪切对局部瑞利-泰勒和电阻漂移波不稳定性的影响

研究了速度剪切对瑞利-泰勒（RT）和电阻漂移波（DW）不稳定性的局部解的影响。使用平板几何形状，并且假定等离子体密度梯度具有有限的空间结构。它证明了速度剪切对这些不稳定性具有完全不同的影响：虽然它稳定了RT不稳定性并引起等电位轮廓的涡流倾斜，但对电阻DW不稳定性产生了非常轻微的影响，并且仅使涡流移动而没有倾斜。
