The utility model relates to the technical field of radio frequency tag detection, and discloses a detection device for ultrahigh frequency radio frequency tags, which comprises a detection table, and the bottom surface of the detection table is fixedly connected with a support base. According to the detection device for the ultrahigh frequency radio frequency tag, through the arrangement of the adjusting assembly, the supporting rod and the adjusting assembly, when the height and the angle of an RFID reader-writer need to be adjusted according to different sizes and shapes of the radio frequency tag during use, an adjusting bolt is screwed, a moving ring is adjusted up and down on the supporting rod, the position is determined, the adjusting bolt is screwed tightly, and then the adjusting bolt is screwed, so that the height and the angle of the RFID reader-writer are adjusted; by rotating the adjusting ball and adjusting the angle of the RFID reader-writer, the reading accuracy is achieved, the situation that after the RFID reader-writer is installed, a large amount of time is needed for angle adjustment is avoided, the sending and receiving angles of radio frequency signals are optimized, interference of external environment factors on the radio frequency signals is reduced, the possibility of misreading and misrecognition is reduced, and the reading accuracy is improved. And the identification rate and the reading success rate of the tag are improved.

A tire tread rubber composite material based on high extraction resistance liquid rubber and a preparation method thereof. The present invention belongs to the field of rubber materials and their preparation. The purpose of the present invention is to solve the technical problems of poor extraction resistance and decreased mechanical properties of traditional plasticizers. The material of the present invention is prepared from olefin rubber, iron-based butyl-pentane liquid rubber, zinc oxide, plasticizer, sulfur, accelerator and antioxidant, and the olefin rubber is mixed with natural rubber, butadiene rubber, styrene-butadiene rubber and iron-based butyl-pentane rubber, and the molecular weight of the iron-based butyl-pentane liquid rubber is 0.5-5w, and the total content of vinyl side groups and propenyl side groups is 30-60%. The present invention introduces iron-based butyl-pentane liquid rubber into the rubber formula, while ensuring the processing performance of the rubber composite material, the extraction resistance rate is increased by 70%, and the mechanical properties of the rubber material are improved, the tensile properties are increased by about 10.34%, and the tear resistance is increased by about 11.54%.

The invention discloses a multi-physical-field scale prevention and removal test bed system for a pipeline, and relates to a scale prevention and removal test bed system for the pipeline, which is characterized in that flowing liquid flows into a test pipeline through potential energy, so that the influence caused by scaling of a pump is eliminated; the pipeline between the upper water tank and the test pipeline is replaced before each test; a thermostat is additionally arranged in the lower water tank, and a constant-temperature water bath tank is additionally arranged outside the upper water tank, so that the influence of temperature on the test is eliminated; the water level switch is additionally arranged in the upper water tank to ensure that the water level in the upper water tank is consistent, so that the flow rate of liquid flowing into the test pipeline is the same. The test influence factors are controlled and eliminated, so that the accuracy and uniqueness of test data are ensured. The analyzed and detected water body returns to the circulating cooling system through the hose, the problems of water body pollution and sewage discharge cannot be generated in the whole descaling and anti-scaling process, and the surrounding environment and the water body cannot be damaged.

Provided is a composition comprising an antibody linked to an oligonucleotide by a disulfide bond wherein the oligonucleotide is specific for the antibody. Also provided is a kit comprising the composition, and a method of detecting one or more targets in a sample by the composition.

The utility model discloses a kind of outside-hung windows with hidden screen, belong to building door and window technical field.The device is through optimization section bar connecting structure and material combination, solve the problem of heat insulation attenuation, structural deformation and the insufficient problem of functional integration degree existing in traditional aluminum-wood window.Window frame, window mullion and sash adopt double heat insulation strip broken bridge structure, cooperate to form continuous heat insulation cavity with reinforced nylon material heat insulation strip;Wood veneer is realized three-dimensional direction mechanical fixing by special adhesive tape and metal section, eliminates assembly gap.Screen system is built-in in window frame structure, through conversion frame integrated screen guide rail and detachable screen.Glass mounting part adopts multiple adhesive tape sealing system, cooperate glass pad block to realize uniform stress.The window type is through the composite structure of metal section bar and wood veneer, while maintaining the natural texture of wood, improve the heat preservation performance and structural stability of whole window, suitable for the outer window system of civil and commercial building.
