提出基于小波尺度图重分配的信号瞬态特征检测方法和瞬时能量估计方法，并应用于轴承在多种轻微故障状况下的振动非平稳特征的检测与表示。
The singal transient feature detection represent method, and a transient energy evaluation method are used based on the reassigned scalogram for the vibration non-stationary feature representation.
结果表明，重分配的小波尺度图能够以较高的时频分辨率表示轴承振动中的非平稳特征，反映轴承的多种故障，瞬时能量估计可以作为分析轴承状态的依据。
Results show that the reassigned scalogram has the signal feature in the time-scale plane with the high resolution, the transient energy evaluation has the transient feature in a more distinct as…
