Abstract: A styled image generation method, a model training method, an apparatus, a device, and a medium are provided. The styled image generation method comprises: obtaining an original human face image; using a pre-trained styled image generation model, and obtaining a target styled human face image corresponding to the original human face image; wherein the styled image generation model is trained and obtained on the basis of a plurality of original human face sample images and a plurality of target styled human face sample images, the plurality of target styled human face sample images being generated by a pre-trained image generation model, and the image generation model being trained and obtained on the basis of a plurality of pre-acquired standard styled human face sample images.

Abstract: A calculable 3D color printing method is used for generating, on a 3D object surface, a user-specified color texture pattern, including: performing modeling and simulated calculation with respect to a motion and a deformation of a PVA film in a traditional water transfer printing process to obtain a mapping function between each of pixels on the PVA film and points on an object surface; and calculating, by using the mapping function, a texture pattern to print on the PVA film. This disclosure further includes a set of mechanical devices and a 3D vision system for realizing precise and controllable water transfer printing which precisely prints a user-specified texture pattern onto an object surface. This disclosure further includes a multiple water transfer printing method, including: partitioning a complex object surface into a plurality of regions, and separately coloring each region, until eventually completing coloring of the entire object surface.

Abstract: According to a method for producing acetic acid by carbonylation of methanol characterized in that an acid having an acid dissociation constant (pKa) smaller than the constant of acetic acid is allowed to be present in the reaction system, acetic acid can be produced by the reaction of methanol and carbon monoxide in a reaction liquid in the presence of a solid catalyst containing rhodium and alkyl iodide, to achieve an enhanced reaction rate of carbonylation of methanol in producing acetic acid in the region at a high carbonylation degree (Ca>0.8 mol/mol) for more efficient production of acetic acid.
