Abstract: A method for preventing and treating pollution plume migration of a permeable reactive barrier including: mounting monitoring assemblies, so as to monitor operation parameters of an active filler in a reactive barrier and a downstream water body of the reactive barrier in real time; determining whether the active filler in the reactive barrier is passivated according to a change state of the operation parameters, and if passivation occurs, performing a depassivation treatment on the reactive barrier; determining whether a gas blockage occurs in the active filler in the reactive barrier according to the change state of the operation parameters, and if a gas blockage occurs, performing a gas guiding treatment on the reactive barrier; and determining whether a microorganism content in the reactive barrier is greater than a preset microorganism value according to the change state of the operation parameters.

Abstract: An information mapping method includes mapping, by a transmitting end device, first information to second information on a delay-Doppler frame. The delay-Doppler frame includes M×N grids, M is the total number of delay indexes, N is the total number of Doppler indexes. The delay-Doppler frame includes at least two subframes, and each subframe includes a first guard interval portion, a first mapping portion, and two second mapping portions. The two second mapping portions occupy grids corresponding to kmax Doppler indexes at a head and a tail of the subframe in a Doppler direction, and the first mapping portion occupies grids corresponding to (N/G?2kmax) Doppler indexes of the subframe; G being the number of subframes in the delay-Doppler frame. Information mapped to second mapping portions at heads of different subframes is the same, and information mapped to second mapping portions at tails of different subframes is the same.

Abstract: The present disclosure provides a field integrated device for automatically shielding and collecting rainwater and simulating rainfall and an experimental method. The field integrated device comprises a roller shutter assembly. A rainfall assembly and a rainwater collecting assembly are fixed on the roller shutter assembly. The roller shutter assembly guides rainwater into the rainwater collecting assembly while shielding the rainwater. The rainfall assembly is connected with a pumping assembly. The pumping assembly transports the rainwater to the rainfall assembly to realize artificial rainfall simulation. The pumping assembly is fixed in a solar module. The solar module is electrically connected with the pumping assembly and a driving assembly in the roller shutter assembly. The solar module is in signal connection with a remote signal end.
