Abstract: The disclosure discloses a method for preparing feed by bacteria-enzyme synergistic fermentation, belonging to the technical field of fermentation engineering. According to the disclosure, Lactobacillus plantarum JUN-DY-6, protease and cellulase are used as a starter, and camellia seed meal or rapeseed meal is used as a substrate. The bacteria-enzyme fermentation product has higher yield of organic acids and flavor substances and better palatability, and can be used for preparing feed additives. The L. plantarum of the disclosure can inhibit growth of harmful bacteria such as Escherichia coli, S. aureus and Salmonella in the intestinal tract of poultry and livestock, and is good for health of the intestinal tract. The method increases the added value of camellia seed meal and rapeseed meal, and is conductive to reuse of waste.

A driving segment of the first right drive element is connected with the right leg-and foot massage portion and is configured to drive the right leg-and-foot massage portion to stretch and retract with respect to the base.

Abstract: Disclosed is a high-resistance resistor based on silicon carbide. The resistor includes a semi-insulating 4H—SiC silicon carbide substrate, a silicon surface and a carbon surface of the silicon carbide substrate are provided with symmetrical atomic-thickness aluminum oxide insulating layers, thicknesses of the aluminum oxide insulating layers are 0.2 nm-2 nm, conductive metal electrodes are formed at two sides of the aluminum oxide insulating layers through evaporation, and thicknesses of the metal electrodes are 100 nm-500 nm. The present disclosure uses a high-resistance resistor based on silicon carbide that has the above structure, makes an ohmic contact electrode on a semi-insulating silicon carbide substrate, thus obtaining a resistor with a resistance of 100 T? or more, and satisfying requirements of the precision measurement industry.

Abstract: The application discloses a memory controller coupled between a memory module and a host controller to control access of the host controller to the memory module, comprising a central buffer coupled between the host controller and the memory module. The central buffer is configured to receive a command/address signal from the host controller via a command/address channel and selectively provide the command/address signal to the memory module. The command/address signal has an identity authentication message for identifying a source.

Abstract: An intelligent massage chair is provided. The chair includes a chair frame and armrests connected on left and right sides of the chair frame. At least one of the armrests is connected to the chair frame through a flipping device. The flipping device includes a base connected to the chair frame and a flipping fixed seat rotatably connected to the base around a rotation axis extending left and right, the flipping fixed seat is fixed to the at least one of the armrests. When the flipping device flips the armrest to a set position, the chair frame has a side entrance on the side of the armrest. The armrest can be rotated open from the side to form a side entrance for users to sit in the massage chair from the left and right sides, which is convenient for users to sit in the massage chair.
