The invention provides a coding gene of coral-derived anticoagulant polypeptide and application, and belongs to the technical field of bioactive peptides. The invention provides an anticoagulant polypeptide GcKuz1. The anticoagulant polypeptide GcKuz1 comprises a mature peptide fragment as shown in SEQ ID No.1. The invention also provides a preparation method of the anticoagulant polypeptide GcKuz1. The polypeptide GcKuz1 is combined with KLKB1 in a thrombin system, so that the anti-thrombus and anti-coagulation effects are achieved, and the polypeptide does not cause hemolysis and cytotoxicity, has no bleeding risk and has good biological safety. The anticoagulant polypeptide disclosed by the invention has the effect of treating thrombotic diseases, such as arterial thrombotic diseases, venous thrombotic diseases and capillary thrombotic diseases.

An optical element and imaging intervention device for light field modulation are disclosed. The optical element includes a lens substrate having a radial direction and a thickness direction perpendicular to the radial direction. A central visual region and a slow-light modulation region are formed on the lens substrate. The central visual region is formed in the middle of the lens substrate, and the slow-light modulation region is arranged around the central visual region. The slow-light modulation region includes multiple photonic crystals arranged in an array on the lens substrate to reduce the group velocity of light passing through the slow-light modulation region. This optical element can effectively control myopia.

The invention provides quick-frozen dumpling wrappers and a making process thereof, and belongs to the technical field of food. The quick-frozen dumpling wrapper is prepared from flour, a modifier and water, the modifier is composed of calcium-sodium stearoyl lactylate, ascorbic acid, modified starch and vital gluten, and the weight part ratio of the flour to the modifier to the water is 100: (3.6-8): (35-45). According to the quick-frozen dumpling wrapper, through compounding of an improver, the problems of frost cracking and boiling belly breaking of the quick-frozen dumpling wrapper are remarkably improved under the condition that the addition amount is smaller.

This invention relates to the field of waste heat recovery technology, and more particularly to a waste heat recovery device and method for power plants. The waste heat recovery device for power plants includes: a tank, sealing plates, and heat exchange components; the tank includes a cylindrical body and end caps located at both ends of the cylindrical body; the sealing plates are disposed at both ends of the cylindrical body, and the two sealing plates and the cylindrical body form a heat exchange chamber, the sealing plates and the end caps forming a flue gas chamber; the heat exchange components are disposed within the heat exchange chamber, with both ends rotatably mounted on the sealing plates, including a first heat exchange component and a second heat exchange component, the first heat exchange component being nested within the second heat exchange component; gears are disposed on the sealing plates, and the rotation of the gears can drive the first and second heat exchange components to rotate in opposite directions. This invention allows fluids far from the heat exchange tubes to directly contact the heat exchange tubes, improving heat transfer efficiency and achieving full heat recovery.

The invention relates to an electric furnace settling chamber fly ash cold bonding ball, a manufacturing method and a using method. The electric furnace settling chamber fly ash cold bonding ball comprises the following components in percentage by weight: 90-95% of electric furnace settling chamber fly ash, 5-8% of limestone and 3-5% of a binder. The manufacturing method of the electric furnace settling chamber fly ash cold-bonded ball comprises the following steps: S1, uniformly mixing the electric furnace settling chamber fly ash, limestone and a binder; s2, forming cold-bonded balls through a ball press machine by adopting a cold-pressing bonding curing forming process; and S3, screening and drying. According to the method, the electric furnace settling chamber dedusting ash and the limestone are made into the cold solid balls through the adhesive, and the cold solid balls are used in converter smelting, so that the melting point of the slag is reduced, the flowability of the slag is improved, and meanwhile, the recycling of the electric furnace settling chamber after dedusting is realized.
