Abstract: Provided is a method for preparing a negative electrode sheet of nickel-metal hydride battery. The method includes steps of: obtaining a substrate roll; unwinding the substrate roll to unroll the substrate roll to form a substrate assembly (100), the substrate assembly (100) having a first-ring exposed segment (110), a middle-ring covered segment (120) and a tail-ring exposed segment (130) which are sequentially connected; and performing a slurry pulling treatment on the substrate assembly (100) to form a first active layer (210) and a second active layer (220) that are formed together on two opposite side faces of the substrate assembly (100), the first active layer (210) being attached to the first-ring exposed segment (110) and the middle-ring covered segment (120), and the second active layer (220) being attached to the middle-ring covered segment (120) and the tail-ring exposed segment (130).

Abstract: The present disclosure provides a pot assembly and a cooking appliance, the pot assembly comprising an inner pot and a food steamer. The inner pot defines a cooking chamber; the food steamer is placed in the cooking chamber, the food steamer is provided with communication holes communicating with the cooking chamber, the food steamer comprises a bottom wall; the inner pot and/or the food steamer is provided with a draining-steaming-cooked rice waterline, and the draining-steaming-cooked rice waterline is higher than the bottom wall of the food steamer. In the pot assembly provided by the present disclosure, by arranging the draining-steaming-cooked rice waterline to be higher than the bottom wall of the food steamer and determining the amount of a solution and the amount of a material to be cooked according to the information of solution and the information of material to be cooked indicated by the draining-steaming-cooked rice waterline.

Abstract: A pulse power device based on an annular ceramic solid state line. The pulse power device comprises several pulse forming lines (2), two charging inductors (1), and several gas switches that are connected as a whole based on Marx voltage superposition. The pulse forming lines (2) are annular pulse forming lines (2), and the annular surface of each annular pulse forming line (2) is provided with one gas switch. The annular pulse forming lines (2) are successively superposed together to form a column structure through the gas switches. Each charging inductor (1) passes through the inner ring of each annular pulse forming line (2) to be disposed inside the column structure. An annular insulation plate (3) is disposed between every two annular pulse forming lines (2).

Abstract: A control method for a rice cooker and the rice cooker are provided. The control method includes controlling a pressure-changing device to change a pressure in a cooking cavity of the rice cooker from a normal pressure to a first pressure, when the rice cooker enters a water absorption stage, and controlling the pressure-changing device to enable the pressure in the cooking cavity to alternate between a second pressure and a third pressure, after the pressure in the cooking cavity is changed to the first pressure.
