The invention relates to a plating method for an anti-reflection film with high transmittance and low reflectivity, wherein the method is the key technology of window glasses and filters of digital cameras, and the technology can further be applied in fields of radiation protection glasses, thermal insulation glasses, window glasses, solar energy utilization and the like. The method comprises the following steps in vacuum plating equipment: (1) pumping vacuum; (2) heating; (3) cleaning ions (Ar and O2); (4) plating SiO2; (5) etching under full oxygen atmosphere (only introducing O2); (6) plating TiO2; and (7) etching under full oxygen atmosphere (only introducing O2), and repeated performing the steps of (4)-(7) until the film system is completed. According to the present invention, the transmittance of the anti-reflection film in the optical wavelength region of 400-700 nm is improved without improvement of vacuum plating equipment requirements, and the reflectivity is further reduced.

The invention provides a CT detector suitable for long samples. The CT detector comprises a whole-shielded radiation protection box and a motion assembly arranged in the whole-shielded radiation protection box through a support, wherein the motion assembly comprises a motion base, a driving rotating assembly and a driven rotating assembly are arranged at two ends of the motion base respectively; a sample holder is deployed at the outer end of the driving rotating assembly and/or the driven rotating assembly; a radiation source detector assembly capable of moving horizontally in the length direction of the motion base is also arranged on the motion base. The CT detector suitable for the long samples has the advantages as follows: the CT detector is small in size and light in weight, can drive the samples to rotate by the aid of the driving rotating assembly, can detect the samples in all directions in combination with horizontal movement of the radiation source detector assembly to realize total-travel helical scanning imaging of the long samples, the detection accuracy is greatly improved, and the detection speed can be increased.

The invention discloses radiation protection clothing combining wave absorbing and shielding technologies. Buttons and/or a zipper of the radiation protection clothing are radiation protection buttons and/or a radiation protection zipper which can absorb electromagnetic waves. The radiation protection buttons and/or the radiation protection zipper are formed by mixed melting of radiation protection raw materials and other plastic raw materials, and injection molding. The radiation protection raw materials include ferrite powders, zinc oxide powders, barium sulfate, graphite, acetylene black, and grapheme powders. The clothing can shield electromagnetic waves and absorb electromagnetic waves, greatly reduce electromagnetic radiation dosage around a human body, reduces electromagnetic radiation repeated pollution of space, and enhance protection effect on a human body.

The invention discloses a radiation protection lining of zonal mat knitting cell metal fiberyarn and a weaving method of the radiation protection lining. The lining is composed of an upper layer, a lower layer and core weft, wherein the core weft is mingled between the upper layer and the lower layer in a weaving mode and is a row of metal fibers or metal wires, both the upper layer and the lower layer of the lining are weaved by adopting soft and moisture-retentive cotton yarn or wool yarn, and the core weft is alternatively weaved with warps of the upper layer and the lower layer so as to tie the upper layer and the lower layer together to form a fabric multilayer entity; the weaving of the core weft and the warp of the upper layer adopts V-shaped fixed tying, and different colors are matched to strengthen decoration; the weaving of the core weft and the warp of the lower layer adopts w-shaped fixed typing, the fixed tying fastness of the core weft is strengthened, and the situation that the core weft comes off due to external forces is avoided. According to the radiation protection lining of the zonal mat knitting metal fiberyarn and the weaving method of the radiation protection lining, the fabric has an electromagnetic wave radiation shielding effect, the moisture-absorbing and soft problems of the surface of the fabric are solved at the same time, the need of wearing comfort is met, and the luster of the metal wires is utilized to generate a decorative effect on the cloth cover.
