对信号进行外延后进行EMD，然后利用掩膜信号对IMF分量进行延拓后再进行希尔伯特变换；
We extend the data before using EMD, and then we extend the IMF based on making signal before using Hilbert transformation.
然后应用SVR方法对系统效率测试原始数据进行双边延拓，对延拓后的数据信号进行经验模式分解。
The comparison of the test data with measurement data shows that the regression and prediction with the SVR method are highly accurate.
