The utility model provides a kind of backlight double-view film, including the base material layer of PET material and the prism function layer of several numbers prisms composition. The base material layer used is PET material, and it is transparent and high in strength, which is conducive to improving the strength of the composite film without affecting the observation effect of the double-view film, and facilitates use and storage. The prism cross section used in the prism function layer has an isosceles triangle structure, which not only meets the double-view effect, but also has good stability. In addition, the UV soft rubber material design of the prism function layer not only has a moisture-resistant effect, but also has the advantage of anti-UV aging, which is conducive to prolonging the service life of the film.

The utility model relates to a cable, in particular to a high-power low-loss radio frequency cable for a chariot radar. The utility model aims to provide the high-power low-loss radio frequency cable for the chariot radar, and the cable has the functions of low attenuation, high power and external electromagnetic interference resistance, and has the characteristics of light weight and high flexibility. According to the technical scheme, the high-power low-loss radio frequency cable for the chariot radar is characterized by comprising a cable core, an inner shielding layer, a middle layer, an outer shielding layer and an outer protection layer, the cable core comprises a conductor, and a first insulating layer, a second insulating layer and a third insulating layer which sequentially wrap the conductor from inside to outside.

The invention discloses a raspberry structure Pd-Sn-O / Pd-Sn composite material, which is obtained by taking stannous mono-sulphate and palladium chloride as raw materials through hydrothermal reaction and calcination, the components are PdO, SnO2 and Pd2Sn, the microstructure is a raspberry structure, and the size of a single nanoparticle is 15-20 nm. The preparation method comprises the following steps: 1, preparing Pd / Sn-MOF; and 2, synthesis of PdO / SnO2 / Pd2Sn is carried out. A gas sensor based on Pd-Sn-O / Pd-Sn is characterized in that under the conditions that the test temperature is 77.32 DEG C and the test humidity is 5%, the response rate to 2000 ppm H2 is 25000-30000%, the response time is 1-2 s, and the recovery time is 180-190 s; the detection gases are respectively H2, NO2, CO, NH3, H2S and CH4; under the condition that the concentration of the tested gas is the same, the selectivity to H2 is extremely high under the condition that the concentration of the tested gas is 1000 ppm, and the response rate of 1000 ppm H2 is 7000-8000%; according to the invention, under the condition that the humidity is 0-90%, the response rate to H2 is achieved, that is, the humidity resistance is achieved, and under the condition that the humidity is 90%, the response rate to H2 reaches 5000-6000%.
