The invention discloses an AI question and answer streaming content word-by-word rendering method based on dual-state control, particularly relates to the technical field of artificial intelligence question and answer front-end streaming rendering, and aims to solve the problem that existing webpage artificial intelligence question and answer lacks dual-state control capability in a streaming pushing scene. The page rearrangement frequency and the memory occupation cannot be stably controlled while the word-by-word rendering continuity is ensured, and the problems of content loss, lagging and out-of-control security filtering are easy to occur when multiple questions and answers are concurrent. The method comprises the following steps: generating a record identifier for each question and answer at a front end, constructing a dual-state management and control object comprising a thinking state container, an answer state container, a buffer area and word-by-word rendering rhythm parameters, and executing field-based complete set analysis, half-package splicing, content unit merging and timed driving word-by-word rendering on event segments of a server; therefore, the question and answer content sequence can still be kept consistent in a long-connection streaming return and multi-round concurrent scene, text presentation is continuous and smooth, and content loss, repeated rendering and page jitter are reduced.

This invention discloses a jet-based rotor flow control system and method, relating to the field of helicopter aerodynamics. It includes an engine bleed air inlet, an air filter, a one-way valve, a high-pressure air source chamber, a pressure reducing valve, and a proportional valve, connected sequentially via pipes. The proportional valve is connected to a pressure damper and an air supply slip ring via pipes. The proportional valve is electrically connected to a power supply and a signal generator. The stator of the air supply slip ring is fixed to the helicopter fuselage, and the rotor of the air supply slip ring is connected to a hollow rotor shaft. The outlet of the rotor of the air supply slip ring is connected to an air supply pipe. An internal air pipe communicating with the air supply pipe is arranged inside the rotor blade. Multiple jet outlets are distributed on the upper wing face of the rotor blade. The aerodynamic excitation generated by this invention has advantages such as high strength, simple structure, and minimal impact on the original aerodynamic profile, showing significant advantages and application potential in rotor retreat blade stall separation control.
