    Abstract: The present invention discloses a POS high-accuracy positioning method under occlusion, comprising: integrating single-point positioning data and differential correction data for solution to acquire high-accuracy position information; implementing a buffer through an RAM of an FPGA to cache the collected position information and a sampling time; when a satellite signal loss is detected by a system, fetching five pieces of position information from the RAM at a time before the signal is lost and five pieces of position information at a time after the signal is reappeared, and filtering the information to obtain filtered data; constructing an equation by using the filtered data, and estimating a signal lost position. By triggering an occlusion algorithm through the FPGA, the present invention improves an ability of a POS system to work in areas with weak satellite signals and meanwhile reduces an operation time, thereby meeting practical needs.

    Abstract: The technical field of enzyme immobilization, and particularly, an organic-inorganic hybrid nanoflower and a preparation method thereof. The organic-inorganic hybrid nanoflower is a flower-like immobilized enzyme formed by self-assembly of a layered rare earth compound as an inorganic carrier and a biological enzyme as an organic component. The layered rare earth compound is Ln2(OH)5NO3.nH2O, where Ln is one or more of La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, or Y, and n=1.1-2.5. The biological enzyme is one or more of α-amylase, horseradish peroxidase, or laccase. A layered rare earth compound is used as the inorganic carrier for the organic biological enzyme to form the flower-like immobilized enzyme. The immobilized enzyme has better stability and higher catalytic performance when compared with a free enzyme.
