Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for a virtual objection distribution method are provided. One of the methods includes: performing an image scanning to a local environment of a user; conducting image identification to an acquired image; acquiring an electronic certificate from a server if an image identifier is identified in the image; saving the electronic certificate; and, in response to a determination that a category count of the received electronic certificates reaches the threshold, sending to the server a virtual object distribution request to cause the server to distribute a virtual object to the user. This method significantly increases interactivity and entertainingness of a virtual object distribution process.

Abstract: A method of allocating virtual objects based on augmented reality (AR) includes displaying, by an AR client terminal of a receiving user, a live map associated with a location of the receiving user. The live map includes a target location to which a virtual object was bound by a distributing user. The AR client terminal of the receiving user scans an image of an environment of the target location. In response to determining that the scanned image includes a preset bound target, the AR client terminal of the receiving user receives information of the virtual object from a server terminal. The preset bound target is associated with the virtual object and the target location.

Abstract: Computer-implemented methods, non-transitory, computer-readable media, and computer-implemented systems for augmented, reality-based, virtual object allocation. One computer-implemented method includes performing face recognition on a scanned image, comprising performing image scanning of a user using a client device to generate the scanned image. An electronic certificate used to obtain virtual objects and sent by a server is received at the client device when one or more facial features are recognized from the scanned image. The electronic certificate is locally stored as a locally stored electronic certificate. Whether a number of types of locally stored electronic certificates reaches a predetermined threshold is determined.

Abstract: The invention relates to a method for eliminating hollow defects in atomized superalloy powder, and pertains to the field of powder metallurgy materials. A ball-milling processing is conducted on the atomized alloy powder to eliminate the hollow defect, obtain solid powder and increase powder utilization efficiency. By controlling mill ball diameters, mass ratio of mill balls with different diameters, mass ratio of ball to powder and ball milling time, a multi-directional impact on the powder is achieved, thereby control powder shape and obtain solid spherical powder. The invention eliminates powder hollow defect by using ball milling process and equipment. This invention with high powder utilization efficiency, short ball milling time and simple operating process, can be used for large-scale preparation and application.

Abstract: A multi-client (e.g., multi-person, multi-user, multi-device, or multi-node) information exchange method includes receiving a first request for a first client to enter a multi-client information exchange interface. The information exchange interface is operable for displaying information sent from clients including the first client. The information exchange interface is provided to the first client according to the first request. An exit request for the first client to exit the information exchange interface is received. The information sent from the clients is deleted in response to the exit request. Subsequent to the exit request, a second request for the first client to enter the information exchange interface is received. In response to the second request, information sent from clients since the exit request was received is displayed.
