The invention discloses a method of a self-organizing network directed route in the air. The problems of being poor in invulnerability, roundabout in route, bad in link reliability, free of high priority level business service quality guarantee and low in network throughput in the method of a self-organizing network route in the air are mainly solved. The realization process is that all nodes obtain the position information of all other nodes by receiving a hello package; when a data package arrives, a current node finds out a next hop node according to a single hop communication distance fallback mechanism and a directed route strategy, inserts the data package into a sender array by delaying different time according to a priority level, and then sends the data package out; if the next hop node does not exceed the multi-package receiving capacity of a media access control (MAC) layer in the process of receiving the data package, receiving of the data package is successful; and if the node is not a destination node, the node is used as the current node, the above process is repeated until the destination node is reached. The method of the self-organizing network directed route in the air improves the route performance of a self-organizing network in the air, and can be used in the route process of the self-organizing network in the air.

The present invention relates to a U-shaped ventilation working face goaf full-face curtain nitrogen injection fire preventing and extinguishing method comprising determining the nitrogen flow rate QN of a main pipeline, and is characterized in that the laying number of nitrogen injection pipes n0=int(Ly / Lb+1). When n0=3, the method comprising steps of (1) laying the first nitrogen injection pipe full face along an inner side of a rear chute at the rear portion of a support, propelling to a position away from a goaf boundary with an LK distance in the working face propelling direction along a coal face, performing leaking stoppage on upper and lower ends, and enabling a control valve of the nitrogen injection pipe to continuously inject nitrogen to the goaf full face; (2) propelling to a position where a distance between two nitrogen injection pipes is goaf nitrogen injection pipeline array pitch Lb along the coal face, repeating the method (1) to lay the next nitrogen injection pipe, and achieving nitrogen injection of the next nitrogen injection pipe; and (3) repeating the method (2) to achieve continuous nitrogen injection to the goaf full face by the third nitrogen injection pipe. A continuous nitrogen curtain is formed at the whole goaf by nitrogen injection, residual coal low-temperature oxidation is suppressed, nitrogen is prevented from rushing into the coal face, the nitrogen diffusion radius is fully utilized, and the nitrogen diffusion effect and nitrogen inerting efficiency are improved.

The invention discloses an SPE (Solid Polymer Electrolyte) electrolysis system used for tritium concentration. The electrolysis system comprises an electrolytic tank system, a tritiated water supply system, a gas-liquid separator, a tritiated water collection system, a hydrogen drying system, an oxygen drying system, a hydrogen collection system, a product oxygen collection and storage tank, a condensation system and a detection and control system. The invention further provides a realization method for the SPE electrolysis system used for tritium concentration. The electrolysis system can meet all process demands of aqueous phase tritium concentration, wherein the processes include a tritiated water circulating concentration process, a hydrogen leakage emergency power-off process, a molecular sieve drying bed continuous treatment process and the like. Meanwhile, due to the tritiated water circulating concentration, the tritiated water concentration can be quantitatively controlled, so that the tritium concentration efficiency is greatly improved and a large amount of tritium-poor hydrogen is obtained.

The invention discloses a power-free aerobic biological treatment method for rural domestic sewage, belongs to sewage treatment (C02F), and mainly aims to solve the problems of large civil engineering quantity, high investment cost, huge aerobic aeration energy consumption and the like existing in the conventional domestic sewage treatment process. According to the technology, a power-free aerobic air channel comprehensive treatment system is invented by using the advantage of rich mosses and bamboo for weaving in rural areas. The method comprises the following steps: introducing sewage into a water distribution groove through a water inlet branch tube valve, and uniformly distributing the sewage at the bottom of the water distribution groove to complete primary natural aeration; introducing the sewage into an upper layer moss filling area, a middle layer moss filling area and a lower layer moss filling area of a bamboo basket in the water distribution groove in a drip irritation way, performing automatic oxygen aeration by using the power-free aerobic air channel comprehensive treatment system to complete secondary natural aeration, and gradually purifying the sewage under the actions of filtration, adsorption, degradation and the like of the mosses and microorganisms. The system has the advantages of no need of manual aeration, no power consumption, no need of building complex buildings, small engineering quantity, no equipment investment, easiness and convenience in operation and capability of realizing unmanned operation, and is suitable for treatment of medium and low-concentration domestic sewage in rural areas.
