说明： EEMD将特殊幅值下的高斯白噪声引入到分解的过程，可以消除上包络和下包络之间存在的拟合误差，从而很好地避免不同尺度下IMF的模态混叠现象，(EEMD can eliminate the fitting error between the upper envelope and the lower envelope by introducing the Gaussian white noise with special amplitude into the decomposition process, so as to avoid the mode aliasing of IMF at different scales,)
