摘要： A method for constructing a porous micro-nano structure, includes: thoroughly mixing glass powders and metal powders to obtain a mixture; coating the mixture on a surface of a substrate, and forming a coating on the surface, wherein a temperature of forming the coating and a melting point of the glass powders comply with the following formula: Tforming≥Tglass−50° C.; and constructing a surface structure of the coating to obtain a porous micro-nano structure coating on the surface, such that a material with a porous micro-nano structure is obtained. The method is simple and has a low cost. The porous micro-nano structure coating prepared has excellent mechanical stability.

摘要： A method for synchronizing virtual and real statuses of a digital twin system of an unmanned aerial vehicle (UAV) includes: performing parameter configuration for a virtual object system and a physical object system of the UAV; performing time synchronization between the virtual object system and the physical object system; detecting an event trigger type, wherein the event trigger type is a training event or a monitoring event; and triggering a corresponding synchronization controller based on the detected event trigger type, such that the synchronization controller performs result synchronization and process synchronization for the virtual object system and the physical object system based on the event trigger type, where a synchronization controller corresponding to the training event is a controller for synchronizing a physical object to a virtual object, and a synchronization controller corresponding to the monitoring event is a controller for synchronizing the virtual object to the physical object.
