We found that in the case of neglecting magnetic shear, the plasma current also can be driven by the shear Alfvén wave and the circularly polarized wave, respectively, the efficiency of current drive in the rotation plasma is independent of the plasma density In addition, it is found that whether m=0 or m≠ 0, the effect of the magnetic shear on the compressional Alfvén wave current drive makes the efficiency be dependent on the plasma density and inversely proportional to it.

当考虑旋转效应而不考虑磁剪切效应时，等离子体平板模型下平面极化压缩阿尔芬波能够驱动旋转等离子体电流，驱动效率也与等离子体密度无关，却与旋转大小成正比，这与Avinash[Phys Plasmas 4，2204（1997）]的结论一致。我们发现在这种情况下剪切阿尔芬波和圆偏振阿尔芬波都可以驱动旋转等离子体电流，旋转效应引起的电流驱动与密度无关。
