| 摘 要： | 本文分析了磁层内哨声波的丝化不稳定性,并计算了增长率.结果表明,对于L(?)4和电场强度约1mV/m的哨声波最大增长率约0.13/1000km,对应最大增长率的横向波长约400km(赤道位置).并进而指出,这种丝化不稳定性有可能是多路径哨声形成的一种非线性机制.

| Abstract: | The filainentation instability of whistler waves in the magnetosphere is analyzed in this paper, and the growth nate is calculated. For propagation path L = 4 and electric field of the wave 1 mV/m, the maximum growth rate is about 0.13/1000 km, the corresponding perpendicular wave length is about 400 km (near the equator region). It is also pointed out that the filaxnentation instability discussed here may offer a nonlinear mechanism for the multi-path propagation of whistlers. |
