The invention relates to a preparation method of an in-situ growth SnS2 resistive random access memory with low power consumption and high switch ratio. The preparation method comprises the following steps: successively processing a Cr layer and an Au layer on the surface of a wafer-level SiO2 / Si substrate to obtain a Cr / Au bottom electrode; the preparation of the SnS2 resistive random access memory with low power consumption and high on-off ratio is completed through a PrCVD method to obtain an in-situ growth PMMA / SnS2 / Au sample, and the preparation of the in-situ growth SnS2 resistive random access memory with low power consumption and high on-off ratio is completed by processing an Ag metal film through a hard mask technology. The two-dimensional material growing in the vertical direction can be prepared, and the power consumption of the resistive random access memory can be effectively reduced. As the target product can be directly grown on the surface of the substrate, the large-area two-dimensional material can be directly deposited on the metal surface. The preparation process is good in stability, the prepared wafer-level SnS2 resistive random access memory can also be used as a master slice for industrial production and can also enter a CMOS process production flow, and industrialization of the low-power-consumption high-switch-ratio resistive random access memory based on the two-dimensional material is greatly promoted.

The utility model discloses a multi-pole ignition device of an impulse voltage generator, and relates to the technical field of impulse voltage generators. The multi-pole ignition device of the impulse voltage generator comprises a bottom plate and an impulse voltage generator body arranged above the bottom plate, and a connecting mechanism and an ignition mechanism are arranged above the bottom plate; the connecting mechanism comprises a mounting part and a moving part; the mounting part comprises a connecting frame and a supporting block; the moving part comprises two lifting frames and two groups of moving wheels; the device has the technical effects that the nut in the connecting mechanism rotates to drive the control frame to move along the first threaded rod, so that the lifting frame descends or ascends, and the moving wheels are in contact with or separated from the ground. By means of the design, the problem that a traditional impulse voltage generator is inconvenient to move is effectively solved, a large amount of manpower and material resources do not need to be consumed during equipment installation and site transfer, and the flexibility and applicability of the device are greatly improved.

This invention discloses a raw material extraction device for detecting anthocyanin content in pure black rice breeding materials, relating to the field of anthocyanin extraction technology in pure black rice breeding materials. The device includes a main structure comprising an extraction tank. A support is fixedly installed on the bottom surface of the extraction tank, and a tank lid is fixedly installed on the upper surface of the extraction tank. A discharge pipe is fixedly connected to the bottom of the extraction tank, and an extraction processing mechanism is provided on the outside of the extraction tank. This raw material extraction device for detecting anthocyanin content in pure black rice breeding materials, through a grinding and air separation unit, can precisely grind the pure black rice breeding materials using grinding rollers, efficiently separating the rice husks from the rice grains. After filtration through a filter screen, the pure rice grains and seed coats enter the extraction tank through the husks, while the broken rice husk impurities are discharged through the discharge chamber. This achieves automated grinding, screening, and conveying of the raw materials, effectively solving the problem of rice husks hindering the contact between the extraction solvent and anthocyanins.
