本文结合数值计算,给出日冕条件下发生回旋不稳定性的条件。经分析得到离子回旋不稳定性较电子回旋不稳定性优先发生的结论,并讨论由离子回旋不稳定性所产生的电场和加速电子流。
Combining with the numerical calculation, the condition of cyclotron instability under the coronal condition is given in this paper. It is concluded that the instability of ion cyclotron is more prevalent than the electron cyclotron instability, and the electric field and accelerating electron current generated by ion cyclotron instability are discussed.
