Abstract: The present disclosure provides a potassium dihydrogen phosphate (KDP) frequency-doubling crystal structure, including a crystal fixing structure, a KDP crystal, a ? polarization tube, and a ? polarization tube; where a ?-polarized laser with a central wavelength of 800 nm enters the KDP crystal through the ? polarization tube, and the KDP crystal converts the ?-polarized laser with a central wavelength of 800 nm into a ?-polarized laser with a central wavelength of 400 nm by frequency doubling and then outputs the ?-polarized laser from the ? polarization tube. Close end bevels of the ? polarization tube and the ? polarization tube are designed into a Brewster angle. The KDP crystal is placed in a vacuum-sealed cavity formed by the ? polarization tube, the ? polarization tube, and the crystal fixing structure, which eliminates a complicated process of crystal coating and prevents the KDP crystal from deliquescing in air.

Abstract: Disclosed is a cone-beam CT multi-directional scanning apparatus which comprises a host machine frame, a cone-beam CT scanning device, a scanning frame and a revolving driving device, wherein the cone-beam CT scanning device is arranged on a body of the scanning frame; and the scanning frame is connected to the host machine frame through the revolving driving device, so that the scanning frame can turn over inside the host machine frame. Scanning on a human body at a vertical position can be implemented when the scanning frame is turned to be in a lying state; and scanning on a human body's lying position can be implemented when the scanning frame is turned to be in a standing state. The cone-beam CT multi-directional scanning apparatus provided by the invention changes the current situation that three-dimensional bone imaging data on a human body's upright position cannot be acquired, and also changes the current situation that image resolving precision on a CT imaging sagittal plane is relatively low.

Abstract: Methods are described for synthesizing stoichiometric LiBC and hole doped Li1-xBC (lithium borocarbide) according to heating processes, such as by both an arc-melting method and a sealed tantalum ampoule method. The arc-melting method requires forming a pellet of uniformly-mixed elemental lithium, boron, and graphite and subjecting it to an arc-melt process sufficient to trigger a self-propagating exothermic reaction. Alternatively, the titanium ampoule method requires sealing uniformly-mixed elemental lithium, boron, and graphite (Li—B—C) in a tantalum ampoule; and heating under sufficient temperature for a sufficient period of time. Hole-doped Li1-xBC (0?x?0.37) can then be produced, such as through vacuum de-intercalation from the LiBC. According to the present invention, the hexagonal crystal lattice remains largely intact, with only slight decreases in lattice parameters upon hole-doping. The samples are intrinsically diamagnetic and are semiconducting in the 2 K to 300 K range studied.
