Abstract: The present invention relates to a method for preparing high-purity vanadium pentoxide from vanadium-bearing shale by all-wet process. The technical solution is: the “Gradient continuous leaching system of vanadium-bearing shale” is used to wet activate and compound leach vanadium-bearing shale to obtain vanadium-containing acid leachate. The “pH adjusting device of the vanadium-containing acid leachate” is used to adjust the pH of vanadium-containing acid leaching leachate. The post-treatment solution is subjected to hydroxime countercurrent extraction after oxidation, and the raffinate returns to the water using in the wet activation and electrodialysis after neutralization, and the loaded organic phase is regenerated by countercurrent reduction stripping. The regenerated organic phase directly returns to hydroxime countercurrent extraction.

Abstract: A display apparatus, comprising: a plurality of light sources arranged into an array, angle selection sheets on the light emitting sides of the light sources, and reflective layers on the sides of the light sources away from the angle selection sheets. The angle selection sheets are used for reflecting light rays of a first incident angle range and transmitting light rays of a second incident angle range, wherein an incident angle value corresponding to the first incident angle range is smaller than an incident angle value corresponding to the second incident angle range. The reflective layers can conduct diffuse reflection on the light rays reflected by the angle selection sheets and the light rays re-enter the angle selection sheets, so that light rays of a second incident angle subjected to the diffuse reflection are transmitted while light rays of a first incident angle repeat the described reflection operation.

Abstract: The invention relates to the field of hydropower scheduling, and relates to a method for short-term generation scheduling of cascade hydropower plants coupling cluster analysis and decision tree. Linear regression technique is adopted to determine a matching relationship of energy production between upstream and downstream hydropower plants. With the relationship, typical generation curves of each hydropower plant can be clustered from lots of historical data. These typical generation curves and impact factors of generation scheduling such as planned daily electricity, reservoir level, and power grid characteristics, are together trained to obtain decision-making library for generation scheduling of cascaded hydropower plants. Thus, the decision tree method can be used to rapidly determine an operational scheme for generation scheduling of cascaded hydropower plants. Finally, a correction strategy for operation constraints is introduced to ensure feasibility of the operation scheme.
