The IMFs obtained by the method are strictly orthogonal each other;
用此方法分解信号所得本征模态信号是严格正交的；
The local energy and instantaneous frequency of the signal can be derived from the IMFs.
信号的局部能量和瞬时频率都可以从其本征模函数中推导出来。
Finally, the prediction results of the failure rate data are obtained by integrating the prediction results of the IMFs and RF.

Another merit is that IMFs and non-IMFs decomposed by the method are orthogonal each other and can prevent IMFs from mode confusing.
该方法的另一个重要特点是分解所得各本征模态函数及非模态函数是严格正交的，不会产生模态混淆。
A new method is introduced to decompose a signal into a set of IMFs (Intrinsic Mode Function) by virtue of fast band-pass filtering.
