Abstract: A barrier structure for bearing a high-energy impact and construction method thereof are provided. The barrier structure includes a supporting pile array arranged between two opposite mountain slope surfaces. The supporting pile array is arranged in a straight line and includes two or more supporting piles. The two or more supporting piles are fixed at a lower part of a mountain. A barrier net is connected to the two or more supporting piles. The barrier net passes through the supporting pile array and extends to the two opposite mountain slope surfaces. The barrier net is fixed on the two opposite mountain slope surfaces. Pull plates are disposed on the two opposite mountain slope surfaces, and one side of each of the pull plates is fixed to a corresponding slope surface of the two opposite mountain slope surfaces through reverse prestressed anchor cables.

Abstract: This application discloses a slope detection apparatus and method based on distributed optical fiber sensing. The apparatus includes: optical fiber measuring units arranged inside a slope and configured to measure acceleration time sequences of a plurality of state parameters of the slope; a demodulator, where the demodulator is connected to the optical fiber measuring units and configured to receive the acceleration time sequences of the slope; and a terminal device, where the terminal device is connected to the demodulator and configured to perform multi-domain coupling analysis on the acceleration time sequences so as to generate a feature cloud map of the slope, perform sub-item detection on slope stability state based on the feature cloud map and preset multi-domain feature parameter indexes so as to obtain a sub-item detection result of the state of the slope.

Abstract: Disclosed is a DACOs-type NNRTIs amino acid ester derivative, a preparation method thereof, a pharmaceutical composition, and an application thereof. The structure of the DACOs-type NNRTIs amino acid ester derivative is represented by formula (I). The DACOs-type NNRTIs amino acid ester derivative represented by formula (I) can be used as HIV-1 inhibitors and for the preparation of a drug for treating and/or preventing immunodeficiency viruses.

Abstract: A content recommendation method, a device, and a storage medium are provided, which are related to technical fields of knowledge graph, big data, and the Internet. The specific implementation scheme includes: determining, among candidate producers, a target producer to whom a private domain content recommendation is performed according to product information of the candidate producers; establishing a recommended product set according to correlation among product information of the target producer; and performing a private domain content recommendation to the target producer based on the recommended product set.
