The multi-component alloy includes at least one of refractory metals and compounds thereof, specifically including tungsten, molybdenum, tantalum, niobium, rhenium, tungsten carbide, tantalum carbide and the like.

Abstract: Disclosed are a fully human broad-spectrum neutralizing antibody against coronavirus, and the use thereof. Specifically disclosed are a fully human monoclonal antibody against an S2 region of coronavirus S protein, a nucleic acid sequence encoding the antibody, and a preparation method therefor. The antibody can effectively bind to and neutralize a variety of coronaviruses in a broad spectrum manner, and can be used for preventing and treating diseases related to coronavirus infection, such as SARS-CoV-2. Further disclosed is the potential use thereof in vaccine design.

Abstract: Disclosed is a psychomotor ability assessment method based on multi-target tracking paradigm, which includes the following steps: analyzing research data of psychomotor ability, determining a plurality of measurement dimensions of psychomotor ability, and designing an experimental task paradigm based on the plurality of measurement dimensions, wherein the experimental task paradigm is used for representing a level of the plurality of measurement dimensions; designing evaluation schemes of the measurement dimension based on the experimental task paradigm; evaluating a ability dimension of a person to be detected based on the evaluation schemes, collecting and processing evaluation data, and calculating a weight value of the ability dimension to obtain an evaluation result of the psychomotor ability.

Abstract: The present invention relates to a substrate of a luminous faceplate of a color projection cathode ray tube and a luminous faceplate which is composed of this substrate. The substrate consists of transparent polycrystalline material, and the luminous faceplate comprises a transparent polycrystal substrate and a luminous layer which is formed thereon. The luminous faceplate using the substrate of the present invention has an advantage over the prior art in the volume of a product, operating power, manufacturing cost, and resolution and so on. Thus, it is widely used in the field of color projection TV, advertisement display and so on.
