    摘要: A method for preparing a supercapacitor with good cycling stability uses NiO@CoMoO4/NF, an activated carbon plate, a KOH solution (6 mol/L), and polypropylene as raw materials, and is implemented through preparation of an NiO@CoMoO4/NF electrode and assembly of the supercapacitor, wherein the NiO@CoMoO4/NF is the anode of the supercapacitor, the activated carbon plate is the cathode of the supercapacitor, the KOH solution is the electrolyte, and the polypropylene is an isolation plate. The NiO@CoMoO4/NF electrode in the supercapacitor of the present disclosure treated with the ductile material can better adapt to volume changes during the charging and discharging process. After 10,000 cycles of charging and discharging, the capacity of the present disclosure has not faded and still maintains 100% of the maximum capacity, with a high specific capacitance of 79.4 F/g, an energy density of 35.7 Wh/kg, and a functional density of 899.5 W/kg.

    摘要: Disclosed are an automatic remote water supply system in a low gravity environment, which includes a water supply unit, an environment detection unit and a control unit. The water supply unit includes a water bag, an air inlet pipe, a water pipe and a water pump on the water pipe. The bottom of the water bag has an air inlet and a water outlet. The air inlet pipe is communicated with the water bag through the air inlet. The water pipe is communicated with the water bag through the water outlet. The environment detection unit is configured to detect environmental information in the ecosystem to which the water supply system belongs in the low gravity environment. The control unit is configured to control the starting state of the water pump according to the environmental information, so that water in the water bag flows out through the water pipe.

    摘要: An in-situ detection component for dissolved gases in liquid-phase media and preparation method of the in-situ detection component, the detection component is a drilled hollow-core light guiding device coated with a liquid-gas separation membrane on the outer surface. The liquid-gas separation membrane directly filters the gases dissolved in liquid-phase media into the drilled hollow-core light guiding device, where the laser interacts with the gases and generates the response signals that are transmitted through the hollow-core light guiding device, to realize the simultaneous dissolved gas separation and detection. The present application substantially reduces the time required for liquid-gas separation process in detection components, allowing for fast and accurate in-situ detection of dissolved gases, and integration of liquid-gas separation and detection procedures.

    摘要: A method for detecting a topological structure of a grounding grid under extremely cold condition, includes the following steps: in a substation in an extremely cold area, determining a measuring area S on a ground surface of a grounding grid according to the positions of branches and nodes of the grounding grid in a selected area, acquiring dynamic current values of the branches and nodes through a current sensor based on TMR tunnel magnetoresistance, and then indirectly acquiring the magnetic induction intensity of the measuring area S through conversion; calculating moduli of first to third derivatives of magnetic induction intensities; and determining specific positions and laying depths of the branches of the grounding grid according to peak distances between main lobe peaks and side peaks between strong peaks of the moduli. According to the method, the calculation amount is greatly reduced, and the detection method has strong anti-interference.
