The present invention relates to the field of underground cavern design, and in particular to a quantitative design method for the spacing arrangement of caverns in a large underground cavern group. Three key parameters are selected: the buried depth of the underground cavern group, the geostress lateral pressure coefficient, and the cavern spacing ratio; the function expression between the displacement value of the key part and the key parameter is obtained by calculation to characterize the relationship between the key parameters of the large underground cavern group and the displacement value of the key part, and then for a specific large underground cavern group project, the buried depth of the underground cavern group and the geostress lateral pressure coefficient are determined values, and the relationship function between the displacement value of the key part and the cavern spacing ratio can be obtained. By drawing a curve graph and taking two groups of characteristic points at both ends of the curve that change approximately linearly, line segments are drawn through the characteristic points at both ends to obtain the intersection of the line segments, and the value corresponding to the intersection is the cavern arrangement spacing ratio of the large underground cavern group. The present invention has the characteristics of being scientific, complete, with clear indicators, and easy to implement, and can improve the overall stability of the underground cavern group.

This invention discloses a six-phase reactor for an energy storage converter, belonging to the field of reactor technology. It includes a first reactor assembly and a second reactor assembly. The first reactor assembly includes a first base, which is composed of a U-shaped support plate and an L-shaped support plate, allowing for independent and stable placement. The second reactor assembly includes a second base, mainly composed of an L-shaped support plate, which is temporarily stabilized during manufacturing using a detachable support fixture. After each reactor assembly independently completes overall impregnation and drying, the support fixture is removed. Then, the surfaces of the terminals and connectors to be connected in parallel are polished and the paint is removed. The two bases are then fixed using base connectors, and the corresponding phase terminals are electrically connected in parallel using a phase-parallel connector to form a six-phase output. This invention, through differentiated base design and fixture assistance, allows the two reactors to be impregnated separately before being connected in parallel, balancing impregnation process quality and electrical connection reliability, and also helps to reduce the overall size of the unit.

The invention discloses a displacement amplification type tuned mass inerter damper for a fan blade and an installation method of the displacement amplification type tuned mass inerter damper. The displacement amplification type tuned mass inerter damper comprises a tuned mass inerter damper body, the fan blade, a steel wire rope and an According to the tuned mass inerter damper, infinitesimal displacement generated by vibration of a fan blade is amplified through the displacement amplification type vibration reduction mechanism according to the lever principle, the inerter disc is driven to do vertical reciprocating motion on the screw rod, the inerter disc and the vibration reduction control spring generate damping force and elastic force, and meanwhile when the rotating speed of the blade changes, the vibration reduction effect is achieved. The centripetal force generated by the tuned mass inerter damper in the direction of the connecting line from the blade tip to the blade root and the gravity of the inerter disc in the direction of the screw also change, and therefore displacement generated by vibration of the fan blade is effectively controlled, and energy dissipation and vibration reduction are achieved. In addition, in the direction perpendicular to the connecting line of the blade tip and the blade root, damping force generated by rotation of the inerter disc when the fan blade vibrates can effectively restrain the inertial effect of the overall structure of the damper, and therefore the efficiency of energy dissipation and vibration control is further improved.

This invention discloses an adaptive drug delivery system for ischemic stroke, its preparation method, and its application. MMP-2 responsive peptide-drug dimers are loaded onto the surface of mesoporous polydopamine for intervention or treatment of cerebral ischemia-reperfusion injury. The system allows for targeted drug delivery based on individual differences in disease progression among patients, precisely promoting brain injury repair. This invention applies MMP-2 responsive peptides to the treatment of ischemic stroke, using mesoporous polydopamine as a drug carrier, providing reactive sites and loading space for efficient drug loading. The chemical reaction between catechol on the polydopamine surface and the thiol groups on the MMP-2 responsive peptides loads the peptide-drug dimers, thereby achieving responsive drug release on the carrier surface. Simultaneously, this invention utilizes the ability of polydopamine to scavenge reactive oxygen species (ROS), rapidly clearing local ROS and reducing acute damage caused by ischemic stroke.
