Provided is a method for adjusting a target object, an electronic device, and a storage medium, relating to a field of computer technology, and in particular, to fields of intelligent transportation, automatic driving, computer vision, and the like. The method includes: acquiring a first bounding box corresponding to the target object and a second bounding box corresponding to a support of the target object; obtaining an association relationship for adjustment of the target object, according to a spatial position where the first and second bounding boxes are located; and moving, according to the association relationship, the target object towards the support, to obtain a third bounding box corresponding to the adjusted target object, where the third bounding box and the second bounding box appear to fit each other.

A 5G-TSN resource joint scheduling apparatus includes: a state information acquisition module, a scheduling decision making module, and a configuration module. The state information acquisition module is configured to acquire bottom-layer network information, and process the acquired bottom-layer network information to obtain state information, the bottom-layer network information includes channel information, gate control list information of a TSN domain, and queue information in a base station. The scheduling decision making module is configured to obtain a result of decision making based on the state information output by the state information acquisition module using a DDPG-based reinforcement learning model, the result of decision making includes whether to allocate resources for a current queue and a number of resources actually allocated to the current queue. The configuration module is configured to convert the result of decision making to one or more instructions understandable by the base station to configure the base station.

An anti-pollution-flashover locomotive roof composite insulator, comprising: a support body, and several groups of sheds arranged side by side along the axial direction that are set around the sidewall of the support body, wherein the sheds protrude out of the sidewall of the support body along the radial direction, the upper end of the uppermost shed is set with an upper metal fitting, and the lower end of the lowermost shed is set with a lower metal fitting. The creepage distance of the sheds between the upper metal fitting and the lower metal fitting is 1085 mm-1095 mm, and the arcing distance between the upper metal fitting and the lower metal fitting is 245 mm-255 mm. The insulator employs a long specific creepage distance in terms of structural design, thus providing a good pollution flashover resistance, and under the same pollution condition, a good pollution flashover resistance that is over twice of that of a porcelain insulator with the same creepage distance may be obtained, and hence it is especially applicable for moderate and serious polluted regions.

An interface breakdown-proof locomotive roof composite insulator. The composite insulator comprises: a support body; and at least five shed groups arranged side by side along the axial direction that are provided around the sidewall of the support body, the at least five shed groups includes: at least four shed groups located on the upper end with each group including a large shed and a small shed; and at least one shed group located on the undermost end with each group including two small sheds. For such a shed structure, it is favorable to tolerate impulse voltage, and it is difficult for the interface to be broken down; the electric field on the interface even does not exceed 3 kV/mm, and even if a gas exists on the interface, it will not break through the interface.

A process for metalizing a ceramic surface or attaching a ceramic to a metal is provided. The process may comprise: immersing the ceramic into an aluminum or aluminum alloy melt, making the ceramic move or stay still relative to the melt to adhere the melt to the ceramic; and then removing the ceramic from the melt to unaffectedly cool the film adhered thereto. The process can attach an aluminum or aluminum alloy thin film having a thickness of several to tens of micrometers on a ceramic surface. The thin film is formed by solidification, and does not have microscopic faults such as oxide film inclusions or pores, therefore having proper physical of mechanical properties of aluminum. Ceramics or a ceramic and a metal can be brazed via the surface metalizing film, the bonding strength of their interface can over the strength of aluminum itself.
