A preparation method and a use of 2D MoSmaterials are provided. Molybdenum source and sulfur powder are used as raw materials, and inert gas is used as carrier gas. Through an intermediate evaporation process, the raw materials are transported to the molten glass surface and deposited into solid molybdenum sulfide. In the subsequent etching-spreading-sulfurization-precipitation process, ultra-high quality and ultra-large area MoSsingle-crystal domains are obtained under normal pressure and without hydrogenation. The single-crystal domain size of the prepared 2D MoSmaterial can reach 1.5 cm, and then grow into a wafer-level 2D MoSmaterial with a size of 2 inches and a thickness of 1-2 layers.

Embodiments of the present disclosure relate to a method and apparatus for updating information. The method may include: acquiring road network structure information of a target road network and vehicle information of a target number of vehicles in the target road network, the vehicle information including initial state information, perception information and positioning information, and the vehicle information being constrained by the road network structure information; selecting a target vehicle from the target number of vehicles; determining, based on a vehicle dynamics model, a reference speed at which the target vehicle passes a preset time step; and updating vehicle information of a vehicle in the target road network based on the reference speed of the target vehicle.

Method and apparatus for updating information

Embodiments of the present disclosure provide a method and apparatus for generating information. A method may include: selecting a three-dimensional object model from a preset three-dimensional object model set based on a to-be-matched object image in a target two-dimensional image; determining, based on a normal vector of a ground plane of the target two-dimensional image, a plane equation of ground corresponding to the normal vector of the ground plane in a three-dimensional space; adjusting a rotation parameter and a translation parameter of the three-dimensional object model in the plane characterized by the plane equation; and generating, in response to determining that a contour of the adjusted three-dimensional object model matches a contour of the to-be-matched object image in the target two-dimensional image, three-dimensional information of an object corresponding to the to-be-matched object image based on the adjusted three-dimensional object model.
