Abstract: The present invention discloses a biaxial supporting device for a rotary opposed piston engine, comprising a cylinder body, a fixing component, a thick axle and a thin axle; the interior of the cylinder body has a cavity; the fixing component is fixed on the outer side wall of the cylinder body; the thick axle is provided with a through hole coaxial with the first axle hole, and is rotatably connected with the through hole; the thin axle is in transition fit with the through hole of the thick axle, and is rotatably connected with the fixing component. The present invention has simple structure, can effectively reduce a diameter difference of two axles to ensure the relatively small diameter of the thick axle and the relatively high strength of the thin axle, and can effectively realize biaxial support of the rotary opposed piston engine.

Abstract: A data communication method, apparatus, and device, a computer-readable storage medium, and a computer program product. The method includes: generating a communication request in response to a trigger operation for a communication control in an embedded subroutine, the communication request being used for requesting to communicate with a target user associated with the embedded subroutine, invoking a communication service plug-in according to the communication request, and communicating with the target user in the embedded subroutine through a first service function provided by the communication service plug-in, and performing, in response to a trigger operation for a second service function provided by the communication service plug-in, service interaction with the target user in the embedded subroutine through the second service function in a process of communicating with the target user.
