This invention relates to the field of chip inspection technology, and more particularly to a chip non-destructive testing system based on embedded current scanning. The system includes a current scanning module, an information acquisition module, a data analysis module, an abnormal scanning region generation module, and a scanning path generation module. Instead of simply performing a higher-density secondary scan of the entire chip, this invention intelligently filters out abnormal scanning regions requiring special attention based on the initial scan results and calculates their scanning priority. This allows valuable inspection time and computing resources to be concentrated on the most suspicious and severe areas, avoiding unnecessary repeated scanning in normal areas. The system dynamically selects the optimal scanning path based on the regularity of the region shape; for example, parallel lines are used for regular regions, and radial lines are used for irregular regions. This makes the scanning path more closely match the geometric features of the defect, obtaining a more complete region characterization with fewer scanning points, resulting in higher path planning efficiency.

This invention discloses a method, apparatus, device, and medium for modeling substation equipment based on random defect embedding, belonging to the field of power equipment simulation modeling. Specifically, it involves: acquiring defect data of target ceramic components in the target substation equipment; determining target defects based on the defect data and a preset threshold, fitting the target defects using a generalized Pareto distribution to obtain scale and shape parameters; constructing a finite element model of the target substation equipment and determining the target region for defect embedding within the finite element model; calculating the total number of defects based on the volume of the target region and the number of target defects per unit volume; randomly generating multiple defect seed points based on the scale parameters, shape parameters, and the preset threshold, and embedding each defect seed point into the target region to obtain the substation equipment model; wherein the defect size of the defect seed points conforms to a generalized Pareto distribution. Therefore, by implementing this invention, the fidelity of substation equipment modeling can be improved.

This invention discloses a pressure calcination process for producing high-purity graphite, relating to the field of graphite production technology, including the following steps: S1, mixing graphite raw materials with a binder; S2, placing the graphite raw materials containing the binder into a mold on a placement platform, and then placing the placement platform and the mold together into a calcination furnace; This invention uses a designed flipping mechanism to drive the mold to flip, realizing the exchange of positions between the upper and lower layers of graphite raw materials, allowing the previously underheated bottom raw materials to directly receive infrared radiation from the resistance wire, eliminating temperature gradients, improving calcination uniformity, and simultaneously working with a transparent pressure plate to compact and flatten the graphite raw materials in the mold before and after flipping, ensuring uniform heating for more complete carbonization of the binder, resulting in consistent density of the green body, and promoting the full volatilization of impurities in various areas of the raw materials, laying the foundation for subsequent graphitization, and improving the purity and quality stability of high-purity graphite products.

This invention relates to the field of polymer composite materials technology, specifically to an aramid composite foam material and its preparation method. The raw materials of the aramid composite foam material include: 0.5-1 parts of meta-aramid chopped fibers; 0.2-0.5 parts of meta-aramid precipitate; 0.05-0.2 parts of thermally expandable microspheres; 2-10 parts of water-based adhesive; 0.5-1 parts of surfactant; and 15-50 parts of deionized water. The preparation method of the meta-aramid precipitate is as follows: meta-phenylenediamine and isophthaloyl chloride are polymerized in a polar solvent to obtain a meta-solvent; the meta-solvent is then fully dispersed in water, followed by solid-liquid separation to obtain the meta-aramid precipitate. The aramid composite foam material exhibits uniform structure, low density, high strength, and temperature resistance with flame retardancy, and the preparation method is green and efficient.
