The invention relates to a premise-based multi-granularity cross-modal reasoning method and device, and the method comprises the steps: carrying out the text splicing of a text premise and a text option, taking the spliced text as a text input, and taking an original image as an image input; extracting coarse-grained multi-modal features and fine-grained multi-modal features after the image and the text are aligned; fusing the coarse-grained multi-modal features and the fine-grained multi-modal features to obtain fused multi-granularity features; and a final prediction result is obtained based on the fused multi-granularity features, and a coarse-granularity feature extraction module and a fine-granularity feature extraction module are used to extract coarse-granularity multi-modal features and fine-granularity multi-modal features after the image and the text are aligned respectively. According to the method, the multi-granularity relation between the image modality and the text premise ...

The invention belongs to the technical field of hydrometallurgy or chemical engineering, and particularly relates to a method for treating nickel-cobalt hydroxides, which comprises the following steps: reducing the nickel-cobalt hydroxides by sulfuric acid to leach nickel, cobalt and other elements, so that the direct recovery rate of nickel and cobalt is greatly improved, then neutralizing the leached filtrate by using the nickel-cobalt hydroxides or recycling NiCO3 to reach a certain pH value, and separating the nickel-cobalt hydroxides from the nickel-cobalt hydroxides to obtain the nickel-cobalt hydroxides. The method comprises the following steps of: precipitating elements such as iron and aluminum, filtering to obtain a nickel-cobalt solution and first-stage iron-aluminum slag, so as to realize the separation of nickel and cobalt from iron and aluminum, carrying out acid leaching, curing and leaching on the first-stage iron-aluminum slag to obtain desiliconized filtrate, well solving ...
