本文分析了极光区上空以低混杂波作为泵波激发静电离子迴旋波的可能性,并计算了增长率。结果表明,当泵波较强时(峰值100mV/m)增长率可达0.5ω_(ci),大于电流驱动不稳定性及离子束流不稳定性等线性理论所可能期待的增长率。从而在某些情况下,离子迥旋波的这种参量激发可能是主要的。 In this paper, we analyze the possibility of low-clutter waves acting as a pump-induced electrostatic ion cyclotron over the auroral region and calculate the growth rate. The results show that when the pump wave is strong (peak 100mV / m), the growth rate can reach 0.5ω ci, which is larger than the expected growth rate of linear theory such as instability of current drive and ion beam instability. Thus, in some cases, such parametric excitation of ion waves may be dominant.
