利用高阶矩统计分析方法对AUREOL－3卫星观测数据进行分析处理，所涉及的信号分别为ELF（＜1kHz）频率范围内的电场扰动Eh（t）和等离子体密度波动δNe／Ne（t）．处理结果表明：利用高阶矩谱分析方法可以很好地识别空间等离子体波-粒相互作用过程中的非线性成分．
The data of AUREOL-3 satellite are analyzed and processed by high-order moment statistical analysis method, and the signals involved are the electric field disturbance Eh (t) and the plasma density fluctuation δNe / Ne (t) in the frequency range of ELF (<1kHz) . The results show that the nonlinear components of the space-plasma wave-particle interaction can be well identified by using the method of high-order moment analysis.
