Research on High-order Spectrum Character for Faults of Gas Valve of Piston Compressors 活塞压缩机气阀故障的高阶谱特征研究
The results showed the high-order statistics method is similar to width amplitude character filtering method but has better results. The high-order statistics method can find wide application in geophysical signal analysis. 结果表明,高阶统计量方法与宽度幅值特征滤波方法相似,而且效果更好,高阶统计量方法在地球物理信号分析中一定会得到更加广泛的应用。
