The invention discloses a staff metabolism simulation system for ground comprehensive tests of a manned spacecraft. The staff metabolism simulation system mainly comprises an oxygen concentration simulation unit, a carbon dioxide simulation unit, a nitrogen simulation unit and a humidity simulation unit. The staff metabolism simulation system is connected with a sealed cabin through pipelines, and air circulates between the staff metabolism simulation system and the sealed cabin of the manned spacecraft. According to an input simulation staff number and each staff metabolism mode, a control system calculates control targets of the heat production quantity, the humidity production quantity, the oxygen consumption quantity and the carbon dioxide increase quantity in combination with a metabolism based empirical formula, and controls a fan, a valve, a compressor, a molecular sieve, a flow controller, a pump and a heater so as to achieve the control targets through data such as temperatures, pressure, flow and oxygen concentration in an acquisition system according to preset control logic. Compared with staff metabolism simulation systems in prior art, the staff metabolism simulation system has the advantages that no staffs are required for participating in the tests, and capacities of a thermal control system and an environment control system are simultaneously assessed; and compared with tests with the staff, test systems constructed by the staff metabolism simulation system are safer, higher in flexibility, longer in continuous running time and fuller in product assessment, and do not occupy cabin volume.

The invention discloses an extraction process capable of increasing the yield of active ingredients in ants, comprising: step 1) selecting ant worm bodies; step 2) placing ant worm bodies in drying equipment, and adjusting the drying equipment so that the drying The drying equipment alternately supplies hot air and cold air to its interior. After the drying process is over, the cold air is finally sent in until the ant worm body drops to room temperature; step 3) put the ant worm body into the carbon dioxide extractor, and perform cell wall destruction twice successively. Wall treatment; step 4) the whole extraction process is divided into 4 stages, from the first stage to the last stage, the flow of carbon dioxide increases successively; there is a first transition section between the first stage and the second stage, The flow of carbon dioxide in the first transition section, the second transition section and the third transition section has a linear increase trend; step 5) after the extraction is completed, the extraction fluid is sent into the separator for separation. The invention improves the yield of active ingredients.

The invention discloses a fire extinguishing type power distribution cabinet based on the principle of high temperature degaussing, which comprises a cabinet body, a plurality of cooling holes are symmetrically opened on the side wall of the cabinet body, sliding cavities are symmetrically opened on the side wall of the cabinet body, and the sliding cavity is symmetrically opened on the side wall of the cabinet body. The inner wall of the cavity is sealed and slidably connected with a slide plate, and the side wall of the slide plate is provided with a plurality of through holes matching with the cooling holes. The top of the slide cavity is fixedly connected with a permanent magnet block, and the top of the slide plate is fixedly connected with a magnet. The lower end of the magnetic block is fixedly connected with the upper end of the magnet through a spring. In the present invention, the temperature in the cabinet reaches the Curie point of the permanent magnet block, so that the permanent magnet block is demagnetized due to high temperature, and then the magnet drives the slide plate to slide down under the action of the spring, so that the through hole and the heat dissipation hole are misaligned, so that the outside air cannot pass through to dissipate heat. The hole enters the cabinet, and the cabinet is subjected to oxygen isolation treatment, and the hydrochloric acid solution and calcium carbonate particles generate carbon dioxide, which increases the concentration of carbon dioxide in the cabinet and accelerates the extinguishing of the fire in the cabinet.
