This invention belongs to the field of polyurethane adhesive production technology, specifically relating to a reaction vessel for polyurethane adhesive production. The reaction vessel includes a tank body, with a stirring motor fixed to the upper end of the tank body. A stirring shaft is fixed to the output end of the stirring motor, and the tank body and the stirring shaft are rotatably connected. Multiple adjustment chambers are sequentially formed inside the stirring shaft from top to bottom. Multiple stirring units are assembled on the outer side of the stirring shaft and inside the tank body. Each stirring unit consists of multiple stirring blades located on the same horizontal plane. This invention uses a vertically positioned sensing plate as a direct viscosity sensing element, which overcomes the oil pressure inside the swing cylinder and drives the sleeve, cross arm, and bushing to produce a corresponding amplitude of horizontal swing. This is transmitted to the stirring blades through an angle adjustment component, achieving automatic adjustment of the stirring blade angle. This allows the stirring blades to dynamically adjust the stirring angle according to real-time changes in the material viscosity.

The application relates to a source adjustable resistance circuit for a high-speed differential amplifier, belonging to the technical field of high-speed analog and radio frequency integrated circuits, comprising a high-speed differential amplifier, a degeneration resistance unit and a control unit; the degeneration resistance unit is composed of a first MOS transistor; the source and the drain of the first MOS transistor are respectively connected to two source nodes of a differential pair transistor of the high-speed differential amplifier, serving as source degeneration resistance thereof, and the gate voltage of the first MOS transistor is generated by the control unit; the control unit is used for generating the gate control voltage of the first MOS transistor. The application replaces a large resistance array with a single MOS transistor, greatly reduces the area, greatly reduces the chip cost, significantly reduces the parasitic capacitance of the degeneration node to the ground, and improves the amplifier bandwidth.

This invention relates to the field of forestry pest and disease control technology, specifically to an intelligent simulation system for the control effect of natural enemies in forestry pest and disease control. The system includes an ecological monitoring integration module, a behavior stage discrimination module, a predation rate inversion module, a stage index mapping module, and a parameter feedback correction module. Based on forest pest monitoring nodes, it analyzes the pest quantity information uploaded by the nodes and determines the sampling point location corresponding to signal changes. This invention integrates forest pest monitoring data, natural enemy activity, and environmental changes in a time series, and introduces behavior stage discrimination based on ecological state information. Combined with paired statistics of natural enemy behavior and pest quantity, it dynamically reveals the ecological response relationship under different behavior stages. The simulated data can automatically adjust the parameter set according to periodic monitoring differences, and the stage effects and trends are promptly mapped into management indicators, making the simulation of control effects more stage-discriminative and ecologically adaptable.
