利用INTERBALL－2卫星上多分量波测量实验（MEMO）在ELF／VLF／LF三个频段进行的高分辨率等离子体波观测结果，通过事件分析，给出了所观测到事件的波传播特性的枯值。结果表明：对于极区千米波辐射（AKR），R－X模式和L－O模式可以同时发生。前者在低频段，后者则发生在频率高端，两者传播是在准平行于地磁场方向的波法线方向上。VLF嘶声发射表明主要是哨声模式，但其它模式也存在。利用波特性分析方法，局域等离子体频率的低频截止L＝0得到精确估值。
Based on the results of high-resolution plasma wave observations in the ELF / VLF / LF ELF / VLF / LF bands by MEMO (Multi Component Wave Measurement Experiment) on INTERBALL-2 satellite, the wave propagation characteristics of the observed events are given through event analysis Valuable. The results show that the R-X mode and the L-O mode can occur simultaneously with polar kilomembrane radiation (AKR). The former is in the low frequency band while the latter is in the high frequency. The propagation of the two is in the direction of the wave normal that is parallel to the direction of the geomagnetic field. VLF hissing shows whistle patterns are predominant, but other patterns also exist. Using the method of wave characterization, the low-frequency cut-off of the local plasma frequency L = 0 gives an accurate estimate.
