This invention discloses a message processing method and related apparatus, relating to the field of message processing. When the current message cache is not full, the main thread receives live messages and submits them to a HandlerThread for asynchronous parsing to obtain different message types. Corresponding caching strategies are then applied, retrieving image cache data from the ImageSpan cache and text cache data from the plain text cache, assembling them into a complete live message, and inserting it into a RecycleView queue for message aggregation caching. The complete live message is then inserted into a scrolling control in the RecycleView list for display. Based on a preset scrolling strategy, the complete live message is directly scrolled and displayed using a SpannableString cache. This invention utilizes HandlerThread for asynchronous message processing, a three-layer caching mechanism to optimize performance, and strategy parsing to decouple rendering logic, ensuring the main thread maintains a high frame rate.

The present disclosure relates to the technical field of centrifugal pump matching tool, and provides a leakage-proof sealing device for centrifugal pump installation, which comprises an outer sleeve, an inner sleeve arranged in the inner part of the outer sleeve, a sealing assembly arranged in the inner part of the outer sleeve, and a lateral connecting assembly arranged on the lateral wall of the outer sleeve and the inner sleeve; a rotating wheel is sleeved on the connecting shaft, and the rotating wheel is in close contact with the inner part of the inner cavity. Through the above technical scheme, the problem that the sealing material is easily worn out due to the continuous friction between the pump shaft and the shaft seal material during high-speed rotation in the prior art, thereby reducing the sealing performance and causing the liquid to leak from the gap between the shaft and the pump shell is solved. The traditional packing seal often uses materials such as graphite wire and hemp rope. When these materials are used to face the high-speed rotating pump shaft, the wear rate is extremely fast, not only frequent maintenance and replacement are required, but also the liquid leakage is difficult to effectively prevent, and there is also the technical problem of environmental pollution.

This invention relates to the fields of graphics rendering and real-time interactive technology, and particularly to a Canvas-based intelligent seat selection method. This Canvas-based intelligent seat selection method first loads the stadium structure in SVG format, and then pre-renders repeating elements as bitmaps for cache reuse using a Canvas rendering engine. Next, it uses a second-order Bézier curve to fit the arc-shaped area and calculates the seat coordinates based on the curvature of the stands. It employs a Redis Bitmap storage scheme to compress the seat status into a binary bitmap, and uses WebSocket to achieve incremental status synchronization. Based on a collaborative filtering algorithm, it generates seat recommendations combined with user historical behavior. After the user selects a seat, the Bitmap is pushed via WebSocket and updated to the client. This Canvas-based intelligent seat selection method not only innovatively uses a collaborative filtering algorithm to achieve intelligent seat recommendations based on user historical behavior, but also reduces user operation latency, reduces server load, and solves the lag problem of traditional seat selection systems when rendering seating charts in large sports stadiums.
