研究了外加旋转磁场对等离子体圆柱的穿透作用。一组适当的磁流体方程的稳态解表明，只要适当地选择磁场的振幅和旋转频率，穿透不受通常的经典趋肤效应的限制。旋转场的增强穿透伴随着产生单向方位电子流，这在纯电阻等离子体圆柱体中完全不存在。
The penetration of an externally applied rotating magnetic field into a plasma cylinder is examined. Steady-state solutions of an appropriate set of magneto-fluid equations show that, provided the amplitude and rotation frequency of the field are suitably chosen, the penetration is not limited by the usual classical skin effect. The enhanced penetration of the rotating field is accompanied by the generation of a unidirectional azimuthal electron current which is totally absent in a purely resistive plasma cylinder.
