The invention discloses a production method of distiller's grain fermentation liquid fertilizer specially applied to roxburgh rose. The distiller's grain fermentation liquid fertilizer is prepared bythe step of evenly mixing 50 to 80 parts of distiller's grain fermentation extracting solution, 0.5 to 1 part of microelement, 5 to 10 parts of seaweed meal, 5 to 10 parts of natural active organism,2 to 5 parts of potassium bicarbonate, 2 to 5 parts of natural active organism and 2 to 5 parts of natural surface active agent. A preparation method of the distiller's grain fermentation extracting solution comprises the steps: evenly stirring 50 to 80 parts of distiller's grain, 50 to 150 parts of rice washing water, 1 to 2 parts of EM microflora fermentation liquid and 0.5 to 1 part of sugar, performing composting fermentation at the room temperature to obtain a distiller's grain fermentation material, stirring and extracting through a sodium carbonate water solution, filtering and performing evaporation and condensation on obtained filtrate until the density is 1.1 to 1.2 to obtain distiller's grain fermentation extracting solution. The distiller's grain fermentation liquid fertilizerdisclosed by the invention has a good use effect, meanwhile can effectively prevent pest and disease damage to the roxburgh rose and is high-efficiency environment-friendly liquid fertilizer.

This invention belongs to the field of firefighting equipment, specifically referring to a high-temperature resistant and flame-retardant fire protective goggles. It includes a main body of the goggles, a frame on which lenses are fitted inside the frame, and buckles on both sides of the frame connected to adjustment straps. The frame is made of flame-retardant and high-temperature resistant TPV composite material, combined with high-temperature resistant and flame-retardant foam, reinforced with heat-resistant polycarbonate lenses, a flame-retardant headband, and buckles. This fully utilizes the core advantages of the overall material—wear resistance, high-temperature resistance, and flame retardancy—allowing the goggles to remain stable in high-temperature environments and continuously provide eye protection. The fire protective goggles of this invention can work stably for more than 5 minutes in a 176.7°C environment without deformation, melting, or breakage, and do not support combustion when exposed to open flames. This effectively solves the problem of traditional goggles easily failing at high temperatures, providing firefighters with a high-temperature resistant and flame-retardant protective barrier that is both protective and adaptable to the complex and harsh working environment of fire scenes.

This invention relates to the field of ice cream processing technology, specifically providing a coated ice cream and its preparation method. The coated ice cream provided by this invention uses mayonnaise as the coating. By controlling the mayonnaise production process and viscosity, this invention ensures that the mayonnaise is evenly dispersed after being coated onto the ice cream surface, reducing protein denaturation caused by uneven mixing. The addition of stabilizers improves the emulsification properties of the coated ice cream product and enhances the hydrogen bond strength between proteins and water. The coated ice cream product obtained by this invention exhibits good melt resistance after being coated with mayonnaise, has a uniform coating thickness without obvious fat particles, does not crack during its shelf life, and is both nutritious and delicious.

This invention proposes a plate-type water-cooled hinge torque balance measurement system for hypersonic wind tunnels, belonging to the field of wind tunnel testing and measurement technology. The aim is to solve the problem in existing technologies where control surfaces are difficult to externally cool due to their thin structure, making hinge torque measurement challenging. In this invention, the aircraft fuselage, wing, and plate-type water-cooled hinge torque balance are connected. The plate-type water-cooled hinge torque balance has an upper cover plate and a lower cover plate at its top and bottom, respectively, with the upper surface of the lower cover plate flush with the aircraft fuselage. The free end of the plate-type water-cooled hinge torque balance, the balance measuring element, and the fuselage mounting base are connected sequentially. The free end of the balance is connected to the control surface being measured via angle lugs. Strain gauges are attached to the surface of the balance measuring element, and the internal structure of the balance measuring element includes a water-cooling circuit. This invention solves the problems in existing technologies where high temperatures significantly reduce measurement accuracy in hypersonic wind tunnel tests, and the thin structure of wing control surfaces makes external cooling difficult, resulting in challenging hinge torque measurement.

This invention discloses a composite material fracturing cap with an embedded weak zone microstructure and its preparation method. The fracturing cap includes a flange frame, a weak zone, and a separation body. The weak zone is an embedded adhesive structure based on a trapezoidal groove. The internal / external load-bearing capacity of the fracturing cap can be adjusted by changing the length and inclination angle of the trapezoidal groove slope in this weak zone. Under missile launch conditions, when the separation body undergoes significant deformation, the adhesive layer between the separation body and the weak zone inclination angle experiences shear and tensile failure, thereby achieving separation of the separation body from the flange and clearing the way for the missile's advance. This invention provides a compact fracturing cap that allows the ratio of the external to internal load-bearing extreme values ​​to be freely achievable within a certain range to the left and right of 1, making it suitable for situations where airtightness and opening performance indicators conflict and where there are strict requirements for equipment space.
