Abstract: The present application provides a suspension device and an X-ray imaging system. The suspension device is configured to bear a tube device of an X-ray imaging system. The suspension device includes a plurality of sleeves and a guide rail assembly. Cross-sections of the plurality of sleeves have substantially the same shape but different sizes. The plurality of sleeves are sequentially arranged. The guide rail assembly is provided between at least one sleeve and another sleeve adjacent thereto. The guide rail assembly includes a protruding member extending along a surface of the at least one sleeve and a sliding member provided on the another sleeve and engaging with the protruding member. The sliding member is capable of moving relative to the protruding member so as to drive the sleeves to move relative to each other.

Abstract: Disclosed is a low-expansion borosilicate transparent glaze, a preparation method thereof, and use thereof in preparation of a glaze product by secondary fusion-cast molding. The low-expansion borosilicate transparent glaze has raw material composition by mass percentage including: 72%-80% of SiO2, 4%-12% of B2O3, 4%-12% of Na2O, 0.1%-4% of CaO, 0.1%-6% of Al2O3, 0-0.05% of Fe2O3, 0-2% of MgO, 0-2% of K2O, 0-2% of ZnO, 0-2% of BaO, 0-2% of ZrO2, 0-0.5% of Li2O, and 0-0.5% of TiO2, wherein a sum of mass percentages of SiO2, B2O3 and Al2O3 is 85%-95%. The preparation method includes steps of: (1) after mixing dried raw materials, melting at 1400-1540° C. to obtain a high-temperature glass melt; (2) cooling the high-temperature glass melt to 1150-1230° C. to mold; and (3) annealing a molded glass at 530-600° C. to obtain the low-expansion borosilicate transparent glaze.
