1) order energy proportion
阶次能量比
1.
Firstly the harmonics can be obtained according to the 3-D spectral map,and then the vibration energy shifting properties among the harmonics was further researched by means of the order energy proportion method based on equal sampling periods.
该方法利用时间三维谱图初步提取系统谐波成分,继而采用等时间采样的阶次能量比对系统振动能量在谐波成分之间的迁移特征进行深入研究。
2) ladder energy
