A targeted corrosion inhibitor for marine reinforced concrete, and a preparation and application thereof. The targeted corrosion inhibitor is a nano silver-loaded nitrite-intercalated layered double hydroxide. The targeted corrosion inhibitor is prepared based on interlayer ion exchangeability of layered double hydroxides and specific recognition of Agto chloride ions.

A method of preparing a modification-free, recyclable and photothermally-driven self-repairing epoxy anticorrosion coating. A bisphenol A epoxy resin is employed as a film-forming material, and a polybasic acid is used as a curing agent. A carbon material is introduced as a photothermal filler to construct a catalyst-free epoxy-anhydride curing system, which is cured at 110-130° C. for 4-12 h to obtain the recyclable and photothermally-driven self-repairing epoxy anticorrosion coating.

A multi-task feature sharing neural network-based intelligent fault diagnosis method has the following steps: (1) separately collecting original vibration acceleration signals of rotating machinery under different experimental conditions, forming samples by means of intercepting signal data having a certain length, and performing labeling; (2) constructing a multi-task feature sharing neural network, having: an input layer, a feature extractor, a classification model and a prediction model; (3) using multi-task joint training to simultaneously train the classification model and the prediction model; and (4) inputting a vibration acceleration signal collected in an actual industrial environment into the trained models to obtain a multi-task diagnosis result.
