Abstract: The present disclosure provides use of an OsMAPK7 gene in transforming non submergence tolerance rice to submergence tolerance rice, and belongs to the technical field of gene function. In the present disclosure, the OsMAPK7 gene has a nucleotide sequence shown in SEQ ID NO: 1. It is found that knocking out the OsMAPK7 gene in rice can transform ordinary cultivated rice that is intolerant to waterlogging into cultivated rice that is tolerant to waterlogging. This process can improve a germination rate of rice seeds, promote root system growth of rice seedlings, and improve a survival rate of rice seedlings under waterlogging. Therefore, this process solves a bottleneck faced by direct-seeded rice production, thereby ensuring the planting area and yield of rice production. The present disclosure further provides a method for converting submergence tolerance of rice, which shows an important utilization value in rice production.

Abstract: A three-side conveyor equipment for silicon wafers is provided, including an insertion container. A bottom conveyor belt and two side conveyor belts are arranged in the insertion container, the two side conveyor belts are arranged opposite to each other above the bottom conveyor belt, the bottom conveyor belt is connected to the side conveyor belts through a transmission assembly, and a linear speed of the bottom conveyor belt is same as a linear speed of each of the side conveyor belts, and each of the side conveyor belts is arranged on a movable bracket that drives the side conveyor belt to clamp or loosen, and the insertion container is provided with two pushing assemblies that respectively push the two movable brackets to move. The two side conveyor belts can clamp or loosen the silicon wafers, and at the same time maintain a same linear speed as the bottom conveyor belt.

Abstract: A material frame unlocking device may include a material frame and an insert slot, a clamping mechanism for clamping a silicon wafer is arranged on the material frame, and an unlocking mechanism for fitting the clamping mechanism is arranged on the insert slot. The clamping mechanism includes two clamping rods capable of opening and closing movements, an end of each of the two clamping rods is provided with a connecting rod, a middle portion of the connecting rod is provided with a hinge point, and an elastic assembly is arranged at one end of the connecting rod away from respective clamping rod, when the elastic assembly is controlled by the unlocking mechanism, the connecting rod rotates around the hinge point, and the two clamping rods are opened to separate the two clamping rods from each other.

Abstract: A worktable for cutting a monocrystalline silicon wafer may include a worktable, a control panel is fixedly mounted on an outer wall of the worktable, a recess is formed on an upper surface of the worktable, a rotatable table is disposed in the recess, a shaft is fixedly connected to a middle portion of the rotatable table, a mounting plate is fixedly connected to each of upper and lower sides of the rotatable table, a clamper is disposed on the mounting plate, a scraper plate is disposed on each of upper and lower surfaces of the rotatable table, and the shaft is rotatably mounted in the recess in the worktable.

Abstract: A residue scraper is provided, which includes a machine frame, which is provided with a clamping unit for fastening a material holder; a scraper unit for cleaning residues on a to-be-cleaned surface of the material holder, and a driving unit that drives the scraper unit to reciprocate along a long side direction of the material holder. In the present invention, the scraper unit is driven by the driving unit to scrape off the residues, thereby achieving a high efficiency to remove the residues.

Abstract: The present invention relates to a relation extraction system adapted to financial entities and fused with prior knowledge and a method thereof, the system at least comprising: a deep pretraining module, for training and generating a deep pretrained model for recognizing attributes of the financial entities; a keyword analyzing module, for extracting and outputting positional information and importance vectors of keywords in a Chinese finance-related text; an attention mechanism module, for encoding the positional information of the keywords to obtain attention masks, and inputting them with entity information into the deep pretrained model to acquire text feature vectors; and an optimal margin distribution model module, for predicting financial-entity relations based on the text feature vectors and the importance vectors.
