说明：  自适应白噪声的完整经验模态分解，在信号处理领域有强大的分解能力，是改进的HHT的一种方法，适合对非线性、非平稳信号进行分解。
(Complete Ensemble Empirical Mode Decomposition with Adaptive Noise It has powerful decomposition ability in the field of signal processing which is an improved method of HHT It is suitable for the decomposition of nonlinear and non-stationary signals)
