The invention provides a skin shape detection tool and a skin shape detection method. The skin shape detection tool comprises a basic platform, a skin supporting assembly, an external force applying mechanism and a skin shape detection mechanism. The skin supporting assembly comprises a plurality of skin supporting pieces which are separated from one another and detachably installed on the foundation platform, and each skin supporting piece is provided with a supporting face consistent with the theoretical appearance of a skin. The external force applying mechanism is used for pressing the skin on the skin supporting piece; the skin shape detection mechanism is used for acquiring molded surface deviation data of the skin, and the molded surface deviation data is a deviation value between the actual shape and the theoretical shape of the skin; due to the fact that the basic platform and the skin supporting assembly are arranged in a split mode, appearance detection of different types of skins can be met only by replacing different skin supporting assemblies, and economy and flexibility of skin appearance detection are improved.

This invention relates to a method for improving protein crystallization efficiency using hydrogel regulation. The method includes the following steps: mixing monomers to obtain a prepolymer solution, adding water and a photoinitiator, stirring to obtain a hydrogel precursor solution; stabilizing the obtained hydrogel precursor solution, then irradiating it with ultraviolet light to obtain a rough hydrogel; immersing the rough hydrogel in water and then drying it to obtain a dried hydrogel; preparing a buffer solution and using the prepared buffer solution to prepare a precipitant; immersing the dried hydrogel obtained in the previous step in the prepared precipitant to swell the dried hydrogel, washing and drying it to obtain a target hydrogel; dissolving the protein in the prepared buffer solution to obtain a protein solution; and dropping the obtained protein solution onto the surface of the obtained target hydrogel to crystallize it to obtain protein crystals. Compared with existing technologies, this invention can effectively solve the problem of low efficiency in protein crystallization while ensuring the quality of protein crystals.

The invention provides a method for preparing a carbon-ceramic composite material brake disc through 3D printing, and belongs to the field of brake discs. The invention discloses a carbon-ceramic composite material brake disc. The light-cured carbon fiber composite material is prepared from the following raw materials: 45-70 parts of modified short carbon fiber, 1-5 parts of boron carbide, 30-40 parts of light-cured resin, 2-8 parts of 75 # microcrystalline wax, 3-8 parts of liquid paraffin, 2-5 parts of aluminum oxide, 2-5 parts of aluminum nitride, 2-6 parts of carbon black, 2-6 parts of octadecanoic acid, 1-5 parts of a modified dispersant, 1-3 parts of an emulsifier, 1-3 parts of ethanolamine, 1-4 parts of sucrose fatty acid ester, 2-6 parts of nitrile rubber powder and 8-20 parts of an organic solvent. According to the method for preparing the carbon-ceramic composite material brake disc through 3D printing, the problems that in the 3D printing process, the extrusion performance of raw materials is poor, printing discharging is uneven, and a nozzle is prone to being blocked can be solved, the curing forming effect and the production efficiency are improved, and the mechanical performance and wear resistance of the brake disc are improved.
