Abstract: The present disclosure provides a split-type swing angle adjustable aerostatic bearing device for rotor static balance and an air flotation support device for static balance of rotating ring-shaped parts, the split-type swing angle adjustable aerostatic bearing device for rotor static balance and an air flotation support device for static balance of rotating ring-shaped parts belong to a field of static balance detection, and aims to solve a problem of low measurement precision of rotor and realize static balance of rotating ring-shaped parts. A gas mold, having a certain bearing capacity, is formed between an outer surface of the air flotation support cover under the bearing base and a concave surface of the upper base, so that the bearing base is floated to realize an automatic centering of the rotor static balancing device.

Abstract: The invention relates to the technical field of agricultural planting, in particular to a controlled-release bacterial fertilizer for peanuts and a preparation method of the special controlled-release bacterial fertilizer. The special controlled-release bacterial fertilizer is composed of an inner layer and an outer layer; after the outer layer is released completely, the inner-layer network structure gradually absorbs water and preserves moisture, and has good slow release and controlled release properties, thereby achieving the gradual release of the inner layer, high fertilizer utilization rate, exerting the efficacy of the microbial agent and facilitating the large-area promotion.

Abstract: The present disclosure provides a magnetron sputtering apparatus, including a process chamber, a bias power supply assembly, and an excitation power supply assembly. The process chamber is provided with a base assembly and a bias guide assembly. A target is arranged at a top of the process chamber. The base assembly is arranged at a bottom of the process chamber and is configured to support a wafer carrier, drive the wafer carrier to move, and heat the wafer carrier. The bias guide assembly is arranged at the base assembly and configured to support the wafer carrier. The bias guide assembly is electrically in contact with the wafer carrier. The bias power supply assembly is electrically connected to the bias guide assembly and configured to apply a bias voltage to the wafer carrier through the bias guide assembly.

Abstract: A device configured to collect to-be-verified identity information of a user and a device configured to verify the to-be-verified identity information may perform a user identity verification method. The device configured to collect the to-be-verified identity information or the device configured to verify the to-be-verified identity information may determine a target identity verification manner applicable to a non-self device from a plurality of identity verification manners based on device information of the non-self device.

Abstract: The present disclosure pertains to a system that may be configured to operate a power grid, including generation participants, consumers, and a controller that administers a market for the power generation participants and the consumers on the power grid. The operation of the power grid may include: performing power grid coordination calculations based upon, at least in part, constraints that pertain to the flow and/or congestion of power on the grid; and managing the coordination calculations by reducing a number of constraints used in the coordination calculations, the managing including a first step of coarse screening of the constraints, a second step of deterministic fine screening of the constraints, and a third step of statistical fine screening of the constraints. This second step may cause identification of constraints that are redundant and/or dominated by other constraints.

Abstract: A user profile generation method and an apparatus. The method includes: sending, by a terminal, at least one short-term user profile generated for a user to a server, where the at least one short-term user profile reflects a behavioral characteristic of the user in first duration; receiving, by the terminal, a long-term user profile generated by the server for the user, where the long-term user profile is generated by the server at least based on the at least one short-term user profile, the long-term user profile reflects a behavioral characteristic of the user in second duration, and the first duration is longer than the second duration; and providing, by the terminal, at least a part of the long-term user profile for a first application.
