Abstract: An abrasive water jet nozzle for strengthening, including a chamber, providing a mixing space; and a strengthening mixing assembly, providing a strengthening mixing of water with an abrasive entering the chamber, wherein the strengthening mixing assembly includes a fluid passage and a water stopper block, wherein the water stopper block is located at an eccentric position on one side of the chamber, and an outlet of the fluid passage faces the water stopper block. The provided abrasive water jet nozzle is capable of fully mixing high speed water with the abrasive particles after the high speed water entering the mixing chamber, so as to ensure the uniformity of the strengthening effect, and the formed abrasive water jet is a large circular fan-shaped jet, which can greatly improve the strengthening quality of the abrasive water jet.

Abstract: A computer device displays at least one virtual scene entrance. The at least one virtual scene entrance corresponds to at least one scene progress of a target virtual scene. The at least one scene progress is determined based on historical interaction behavior of a target object in at least one virtual scene. The computer device transmits a loading request to a first server in response to a trigger operation on a first virtual scene entrance in the at least one virtual scene entrance. The loading request is used for instructing the first server to run the target virtual scene based on a first scene progress corresponding to the first virtual scene entrance. The computer device receives, from the first server, a scene picture of the target virtual scene. The computer device displays the scene picture in response to receiving the scene picture.
