The invention relates to a sample preparation and measurement method for compression of a metal material with high thermal conductivity. The preparation method includes the following steps in sequence: Ⅰ. Take a high thermal conductivity metal material sample to make a metal cylinder. The diameter of the metal cylinder is Ф8 mm to Ф10 mm, and the length is 10 mm to 15 mm. Point as a mark; Ⅱ. Drill a blind hole with a diameter of Ф1.6mm to Ф2.0mm and a depth of 1.8mm to 2.2mm at the mark; Ⅲ. Select a wire material of the same material as the metal cylinder or copper material to make a plug pin; Ⅳ. Place the negative end of the K-type thermocouple wire and the positive end of the K-type thermocouple wire on both sides of the blind hole, and plug the blind hole with a plug pin. The measurement method is to measure the sample on a thermodynamic simulation testing machine to obtain the stress-strain curve of the copper alloy. The process of sample preparation and measuring method of the present invention is simple and easy, and the result of rheological stress test data is accurate and stable.

The invention belongs to the technical field of renewable energy generation and electric power supply, and specifically relates to an intelligent balanced power-supply system with multiple electric powers and multiple electric power storage, and a method. Through a multiple electric powers and multiple electric power storage intelligent balanced power-supply control technology and the control method, using multitask parallel control and management, the multiple electric powers and multiple electric power storage are allocated evenly and intelligently, so that defects exist in the prior art are solved, and integrated management, parallel and complementation, balanced allocation, reasonable and efficient of the multiple electric powers and the multiple electric power storage. The system and the method ensure that need of user's loads for electricity is satisfied by a plurality of ways. The system realizes stabilization of unstable new energy electricity through intelligent balancing and auxiliary charge, and makes electricity generated by renewable energy directly invert to power supply of the user's loads. Intermediate steps and transforming times from the renewable energy generation to electricity utilization by the users are reduced, and an electricity utilization rate of the renewable energy generation is improved. Meanwhile, system configuration is also saved. In conditions of reducing hardware of power transformation and making a renewable electric system satisfy the power supply that same users' loads need, the system reduces allocation of storage batteries and system investment scale, and improves utilization rates of investment and resources.

The invention discloses a production process of high freshness-locked canned corn kernels, which comprises the following steps: step 1, pretreatment: peeling fresh corn ears, precooking, threshing, screening, cleaning, and drying; step 2, grain selection Step 3: Clean and sterilize the empty cans: Clean and sterilize the empty cans; Step 4: Seal the cans: Put the screened grains into the empty cans and seal them; Step 5 , Sterilization: Sterilize the sealed cans in the sterilizer; Step 6, Drying: Dry the surface of the sterilized cans; Step 7, Vacuum inspection; Step 8, Spray code and label, finished product storage; The invention cleans and sterilizes empty cans before filling to avoid uncontrollable factors and ensure the rate of good products; the invention cleans and sterilizes empty cans through cleaning, drying and steaming, which has high efficiency and good effect, and ensures processing efficiency. Promote.

The invention discloses a fat stem cell-ECM modified SIS composite engineered bone and a preparation method thereof. The microstructure of the composite engineered bone includes a SIS collagen fiber skeleton, human fat stem cells and an extracellular matrix layer, and the extracellular matrix layer is composed of MC3T3‑E1 Cell-guided and secreted matrix proteins and polysaccharides, the extracellular matrix layer covers the surface of the SIS collagen fiber skeleton, and human adipose stem cells adhere to the extracellular matrix layer; the composite engineered bone has high mechanical strength and is highly similar to natural The microstructure of bone can provide good tissue support at the initial stage of implantation in the body, and can provide an excellent osteogenic microenvironment for stem cell implantation. After implantation, human adipose stem cells can rapidly proliferate and differentiate into osteoblasts, and promote the healing of large bone injuries. Rapid repair; in addition, the composite engineered bone has pure natural endogenous characteristics, which can avoid uncontrollable factors caused by the introduction of foreign substances / genes, etc., has good safety, and has broad clinical application prospects in the field of bone regeneration .
