LMS的搜索方法程序，实现自适应的快速的方法的实现。(The LMS search method program 1)

小波包分析提取振动信号中的特征频率，与理论分析结果相比，用于建立主成分分析模型。( Wavelet packet analysis to extract vibration signal characteristic frequency, Compared with the results of theoretical analysis, Principal component analysis model for establishing.)

说明：  对国际水质污染与控制协会（IAWQ）推出的活性污泥2d号模型（ASM2d）进行优化,使之能够模拟含有菌胶团的污水处理工艺。使用改良后的ASM2d模型模拟并分析了有机物、氮和磷在DE型双沟式氧化沟中的降解过程。(Activated sludge model 2d(ASM2d)proposed by IAWQ was modified. and it was used to simulate wastewater treatment containing biomass flocs. Combined with the operation parameters of a double-ehanne1 DE-oxidation ditch, a calculated model was built to simulate carbon, nitrogen and phosphorus degradation processes.)
