Confronted with severe and ubiquitous environmental problems, Fenton-like activation induced by oxidants (e.g., hydrogen peroxide, persulfate, peracetic acid and periodate, etc.) (Eqs. (1), (2), (3), (4), (5)) have been diffusely investigated due to superior oxidizing capacity and environmental friendliness [1], [2], [3], [4]. However, in Fe-based Fenton-like systems, the sluggish recovery of Fe2+ from Fe3+ (rate-determining step, Eqs.

Loading metrics Open Access Peer-reviewed Research Article Abstract The amplitude and frequency of the mechanical bearing fault vibration signals vary with time, and which are non-stationary and non-Gaussian process. The fault signals belong to α stable distribution, and the characteristic index 1 < α < 2, even the noises are α stable distribution in extreme cases. The existing linear chirplet transform (LCT) degenerates, even fails under α stable distribution environment.
