Abstract: A magnesium-based solid hydrogen storage material with liquid phase regulation function and a preparation method thereof and an application thereof in an all-solid-state battery are provided, belonging to the technical field of new energy. The magnesium-based solid hydrogen storage material with the liquid phase regulation function includes following raw materials in percentage by mass: 95% of magnesium hydride and 5% of lithium borohydride. Lithium borohydride as an ionic conductor is dispersed on a surface and matrix of magnesium hydride, which provides channels for the rapid hydrogen storage of the magnesium hydride-based materials.

Abstract: The present invention relates to the technical field of mining instruments, and discloses a sensing method for collecting multivariate information at a goaf side of chutes based on scraper conveyors, wherein gesture sensors are provided at a goaf side of the chutes of a scraper conveyor; building an equivalent model of the chutes, fusing constants and variants of relative information and distance measurements methods, determining collection of multivariate information of detection bodies of the gesture sensors of the chutes and combinational logic algorithms thereof; and sensing gesture changes of the chutes by the detection bodies of the gesture sensors of the chutes and conducting collection of the multivariate information and analyzing relative changes and trends of gestures between the chutes. The present invention can further improve detection real time properties, accuracy, coverage, reliability and environment adaptability compared with other measurement methods.
