得到了由等离子体密度变化和波数k⊥=m/r组合产生的势阱中的压缩Alfven本态模的谱，并讨论了其对射频电流驱动的重要性。发现平行波数小且频率低于离子回旋频率的模式对电流驱动有吸引力。
The spectrum of compressional Alfven eigenmodes localized in the potential well created by a combination of the variation in plasma density and the wavenumber k⊥=m/r is obtained, and its importance for radio frequency current drive is discussed. It is found that modes with small parallel wavenumbers and frequencies below the ion cyclotron frequency are attractive for current drive.
