从理论上研究了环形等离子体中与磁场倾斜传播的波轨迹。结果表明，适当入射角的常波在第一个转折点处模式转换为非常波，并在第二个转折点附近通过回旋或折叠曲线时进一步转换为电子伯恩斯坦波，并在到达回旋共振层之前被回旋阻尼带走，导致局部电子加热。
Wave trajectories propagating obliquely to the magnetic field in toroidal plasmas are studied theoretically. Results show that the ordinary wave at the appropriate incident angle is mode converted to the extraordinary wave at the first turning point and is further converted to the electron Bernstein wave while passing a loop or a folded curve near the second turning point and is cyclotron-damped away, resulting in local electron heating, before arriving at the cyclotron resonance layer.
