The invention provides a technological method for repairing an air void in a soft instrument board, a special filling body and a special device of the technological method. The method comprises the following steps: (1) respectively forming an exhaust groove and a pouring channel in the top part and the bottom part of some section of the air void in one side of the rear surface of a coating, wherein the exhaust groove and the pouring channel are communicated with the outside; (2) respectively fixing an exhaust pipe and a pouring pipe in the exhaust groove and the pouring channel; (3) applying a certain of pressure to the coating surface corresponding to the position of the air void, then pouring the filling body into the air void through the pouring pipe until the exhaust pipe is reached; (4) stopping applying the pressure to the coating surface after the filling body is cured, so as to finish the repairing. With the adoption of the method, the air void formed in the production of the soft instrument board can be repaired, and a defected product can be normally put into use after being repaired, so that the production cost can be saved.

The invention relates to a strengthening measure for repairing the polluted soil plant, in particular to a method for combined repairing the soil polluted by heavy mental lead. The method is that the Petunia is planted on the soil which contains the polluted lead. When the Petunia becomes mature, mixed chelating agent is added to the soil. The mature Petunia as a whole are removed or grained after the soil balances for 10 to 15 days, thus achieving the purpose that the Petunia repairs the soil polluted by the lead. The added quantity of the mixed chelating agent is 7.5mmol / kg soil. The strengthening measure adds the mixed chelating agent when maturing to strengthen the total amount of the lead which is richly collected by the Petunia above the soil, and to grain the Petunia above the soilto realize the purpose of treating the soil polluted by the lead which is characterized by high efficiency of repairing, strong feasibility, greatly reduce the environmental risk and harm to the human health, etc.

The invention relates to a device for crack monitoring and repairing of wing components and a method for crack monitoring and repair of wing components, belonging to the technical field of aircraft component performance safety monitoring equipment. The invention aims to form a crack monitoring and repairing device for wing components by electrode sheets, single-chip microcomputers, batteries, filters, thermal imaging detectors, and galvanometers; The metal fatigue accumulated by vibration will cause different degrees of cracks, and the crack monitoring is realized by using the surface current generated by the electrode sheet and the ammeter monitoring current, and the electrode sheet passes a strong current to the cracked area to make the metal at the crack close to the melting point to automatically repair the crack; The filter eliminates interference waves to ensure the normal crack monitoring; the thermal imaging detector monitors the temperature of small metal pieces when cracks are repaired; the single-chip microcomputer integrates monitoring information and control devices to complete crack repair; the battery provides weak and strong currents required for crack monitoring and repair. The device can detect and eliminate safety hazards formed by metal cracks in wing components.

The invention relates to the technical field of branch line fixing devices, and discloses a quick branch line fixing device for circuit arrangement of lamps, which includes a housing, a fastening mechanism for fixing and connecting external objects, and a branch line for branching lamp lines. Wire mechanism, and the connecting mechanism used for detachable connection with the lamp, the fastening mechanism, the branching mechanism and the connecting mechanism are all arranged on the housing; in addition, the present invention also discloses a method for arranging the lamp by using the above-mentioned quick branching fixing device The wiring method of the line. The fast line-splitting fixing device proposed by the present invention is provided with a fastening mechanism, a line-splitting mechanism and a connecting mechanism on the housing, and the fixing position of the entire fast-splitting line fixing device is determined through the fastening mechanism, and then the lamps are tapped through the line-splitting mechanism Lines to avoid potential safety hazards caused by entanglement between wires; at the same time, it is detachably connected to the lamp through the connecting mechanism. Therefore, the problem of how to quickly and safely realize the line layout and position change of the lamps is solved.

The invention discloses a micro-milling repair technical method for the laser damage of the surface of a large-diameter KDP crystal element, and belongs to the technical field of repair machining of optical materials and optical elements in order to solve the problems that during repair of laser damage points of the surface of a soft and fragile KDP crystal element, the repair outline is simplex,the repaired surface quality is poor, and the efficiency is low.
