4results about How to "Guaranteed repair efficiency" patented technology

This application provides a method, apparatus, device, and storage medium for error reproduction and repair, applied to electronic devices, which include flash memory chips, sensors, and a background monitoring module. The method includes: monitoring runtime errors during the operation of the flash memory chips; when a target runtime error is detected, obtaining the target runtime log of the target runtime error; extracting keywords from the target runtime log to obtain target keywords; when the target keywords include preset keywords, obtaining the corresponding target input data, target program code, and target runtime segment based on the target runtime log; obtaining the target physical environment parameters corresponding to the target runtime segment through the sensors; obtaining the target runtime environment parameters corresponding to the target runtime segment through the background monitoring module; and performing error repair based on the preset keywords, target physical environment parameters, target runtime environment parameters, target input data, and target program code, thereby achieving efficient error reproduction and repair.

The invention discloses a microcapsule and a preparation method thereof, and self-repairing polyurethane and a preparation method and application thereof, relates to the field of polyurethane materials, and solves the problems that the self-repairing process of the self-repairing polyurethane in the prior art depends on non-physiological stimulation conditions, the cytotoxicity is high, the biosafety is insufficient, and the application requirements in the field of biomedical instruments are difficult to meet. The invention discloses a preparation method of self-repairing polyurethane, which comprises the following steps: blending a prepolymer I, a prepolymer II and a solvent, adding an Arabic gum aqueous solution and a chain extender, and adding triethanolamine to obtain a suspension containing microcapsules; and washing, carrying out solid-liquid separation, and freeze-drying to obtain the microcapsule. Adding the microcapsules into the polyurethane dioxane solution, uniformly stirring, pouring into a mold, and heating or freeze-drying in vacuum to obtain the self-repairing polyurethane. The microcapsule provided by the invention has excellent biocompatibility, solvent resistance and mechanical properties, the self-repairing condition of the self-repairing polyurethane is mild, and the application requirements in the field of biomedical instruments are met.

The application discloses the technical field of environmental remediation and relates to an in-situ chemical treatment device and method for soil and underground water remediation, which comprises a mixing device, conveying equipment and a support, the support is provided with a mounting plate and a driving piece for driving the mounting plate to ascend and descend, the mounting plate is provided with an injection assembly, the injection assembly comprises an injection head in communication with the conveying equipment and two cover bodies for covering the bottom end of the injection head, the injection head is provided with a driving assembly for driving the cover bodies to move, the bottom end of the injection head is covered by the two cover bodies, the outlet of the injection head is separated from the outside world, the soil cannot enter the inside of the injection head when the injection head is inserted into the soil, the injection head is prevented from being blocked, and the remediation efficiency is ensured.

The utility model relates to the field of inner lining pipe traction technology, and disclose a kind of inner lining pipe traction equipment for ultraviolet light curing pipeline repair, including soil layer, the inside of soil layer is equipped with old pipe, the connecting place of pull block and cleaning plate is cavity, and the outside of cleaning plate and the inside of old pipe contact. The utility model is wound with traction line one on the surface of take-up drum, traction line one will drive pull block to move to the left side of soil layer, when due to the outside of cleaning plate and the inside of old pipe contact, and the connecting place of pull block and cleaning plate is in cavity, so that in the process of pull block moving to left side, the sundries inside old pipe will be spaded, and be collected by the cavity of cleaning plate and pull block, so that the sundries appearing in old pipe is cleaned, so that in the process of repair, there will be no sundries between inner lining pipe and old pipe to block, reach the efficiency of guaranteeing repair.
