A fiber formed from a resin including a silicone-modified polyurethane resin comprising the reaction products of a polyol (A), a chain extender (B), an active-hydrogen-group-containing organopolysiloxane (C), and a polyisocyanate (D), wherein the active-hydrogen-group-containing organopolysiloxane (C) contains an active-hydrogen-group-containing organopolysiloxane (C-1) having a carbinol group atonly one terminal.

The invention discloses an anti-blocking rapid vacuum preloading and solidifying method for flow-state mud with straw as drainage bodies. According to the method, straw bales are inserted into the flow-state mud to form the multiple vertical straw drainage bodies, a straw weaving carpet is arranged on the surface of the flow-state mud in a paved manner, and the straw weaving carpet is connected with the vertical straw drainage bodies in an overlapped manner; pipelines are arranged on the surface of the straw weaving carpet in a paved manner to form a drainage pipe network, a vacuum pump is connected with one end of the drainage pipe network, and the other end of the drainage pipe network is provided with a ventilation valve; the vacuum pump is opened, the ventilation valve is adjusted to control the vacuum degree in a sealing membrane, loading-type cyclic loading is adopted, it is guaranteed that pre-set vacuum negative pressure is loaded in the sealing membrane, the flow-state mud is solidified rapidly, and drainage is carried out. The condition that the drainage bodies are blocked by the flow-state mud can be avoided, the agriculture straw can be fully utilized, and environment pollution caused when the agriculture straw is wasted is avoided.

This invention is about a functional after-operation isolation membrane and method for making same. The functional after-operation isolation membrane is composed of the drugs taken by biodegradable isolation membrane host material, and the drugs contain antiphlogiston drugs, fibrin inhibitor drugs, calcium channel inhibitor drugs, anticoagulant drugs and antibiotics drugs or one or several kinds of Chinese patent drugs; while the isolation membrane host material is made of one or several kinds degradation rate differed materials, whose half-decay times are 1 week to 6 months. Alerting membrane materials kinds and charging amount, drugs kinds and charging amount and isolation membrane layers can make multifunctional, degradation rate different and drug-release characteristic different functional after-operation isolation membrane products, so as to adapt to different using demands. Experiments prove that this functional after-operation isolation membrane can effectively accelerate tissue healing after operation, diminish infection and prevent after-operation adhesions.

The invention discloses a dust sucking and removing system in the technical field of environmental sanitary equipment. The dust sucking and removing system comprises a sweeping brush, a dust collecting hopper, a coarse filtering mechanism and a fine filtering mechanism; a draught fan which can cause the internal negative pressure of the fine filtering mechanism is arranged in the fine filtering mechanism, the coarse filtering mechanism is fixedly installed on the dust collecting hopper and provided with a dust falling barrel, and the dust falling barrel is communicated with a dust collecting cavity; the fine filtering mechanism is provided with a dust discharge barrel; when sweeping is performed, the air outlet side of the coarse filtering mechanism is close to the air inlet side of the fine filtering mechanism, and an outlet of the dust discharge barrel is close to a dust discharge port. The system further comprises a turnover mechanism which comprises a lever, a rotating shaft and a turnover oil cylinder, the lever is rotatably installed on a frame through the rotating shaft, one end of the lever is fixedly connected with the dust collecting hopper, the other end of the lever is hinged to a piston rod of the turnover oil cylinder, and a cylinder barrel of the turnover oil cylinder is hinged to the frame; when the system is in a dust pouring state, the air outlet side of the coarse filtering mechanism is separated from the air inlet side of the fine filtering mechanism, the outlet of the dust discharge barrel is separated from the dust discharge port, and therefore dust or sundries generated in the cleaning process can be conveniently poured.

The invention relates to a method for detecting distribution of lateral line canals of fish, which relates to the technology of detection of sensory organs of the fish. The invention aims to solve the technical problems to provide the detecting method, which has the advantages that: the operation is simple and convenient, dye injected into the lateral line canals is not easy to fade, and the shapes and the structures of the lateral line canals are easy to observe. The method has the technical scheme that a fish sample is adopted, and is characterized by comprising the following steps of: using 10 percent of formalin to fix the fish sample for 48h, or mixing commercially available 10ml of 37 percent to 40 percent of formaldehyde solution and 95 ml of distilled water to fix the fish sample for 48h; washing the fish sample by using tap water for overnight, and removing formalin residues of the fish sample; putting the fish sample into formic acid solution with the concentration of 5 percent, and carrying out decalcifying for 12h so as to soften bone tissue; and injecting the dye from a temporal upper tube by using 5ml of medical injector, wherein the dye is a red mixture, which is prepared by the following steps of: pulverizing 5g of ABS (acrylonitrile-butadiene-styrene) plastic, adding into 60ml of acetone, mixing uniformly, and adding 0.5g of solvent red.

The invention discloses a pressure equalizing chamber, a mounting method thereof and a three-dimension space multi-point pressure measuring and cross section type gas flow measuring device containing the pressure equalizing chamber. The pressure equalizing chamber is of an isosceles triangle thin wall cavity structure, two waist edges of an isosceles triangle are each continuously provided with one or more pressure measuring openings, and all the pressure measuring openings are communicated with a thin wall cavity. By the adoption of the three-dimension space multi-point pressure measuring and cross section type gas flow measuring device, multiple pressure measuring points are arranged at different streamline positions in a three-dimension space, and due to the fact that the pressure measuring cross section exceeds the pressure measuring cross section designed by any existing measuring technology, the pressure equalizing chamber, the mounting method thereof and the three-dimension space multi-point pressure measuring and cross section type gas flow measuring device are particularly applicable to the occasion that the flow speed of a large pipe is unevenly distributed; besides, due to the special thin wall cavity structure of the pressure equalizing chamber, ash accumulation does not occur easily, ash removing needle design is further adopted, and the ash accumulation tendency is reduced to the maximum degree; the gas flow measuring device has the remarkable advantages of being resistant to blocking, resistant to wearing, resistant to high temperature, high in measuring accuracy, stable in measurement value and the like.
