Abstract: Partial bandwidth radio transmission method and device, base station and user equipment are provided. The method includes: configuring a first common control channel transmitted on an anchor sub-band; configuring at least one sub-band other than anchor sub-bands, and a second common control channel transmitted on the at least one sub-band; scheduling at least one partial bandwidth UE to the at least one sub-band, and transmitting configuration of the second common control channel and the at least one sub-band to the at least one partial bandwidth UE; and obtaining a transmission time of a synchronization signal block in the anchor sub-band, and transmitting the second common control channel to the at least one sub-band based on the transmission time, wherein the second common control channel includes a reference signal for demodulation. UE can receive and transmit data using partial bandwidth among a relatively large system bandwidth, which improves system efficiency.

Abstract: A flexible substrate has at least one bendable region. The flexible substrate includes a flexible base, a first electrode layer disposed on the base, a first insulating layer disposed on a side of the first electrode layer away from the base, and a second electrode layer disposed on a side of the first insulating layer away from the base. The first electrode layer includes at least one first detection electrode, and the second electrode layer includes at least one second detection electrode. An orthogonal projection of a first detection electrode on the base overlaps at least partially with an orthogonal projection of a second detection electrode on the base. A region where orthogonal projections of the first detection electrode and the second detection electrode on the base are located overlaps with a bendable region.

Abstract: Disclosed are a method and system for producing hydrogen peroxide, the method comprising: 1) carrying out a hydrogenation reaction on a working solution containing an alkylanthraquinone in the presence of hydrogenation catalyst particles and hydrogen, separating the resultant to obtain a circulating slurry and a hydrogenated solution, and recycling the circulating slurry; 2) dividing the hydrogenated solution into two streams, and regenerating the first stream of the hydrogenated solution to obtain a regenerated hydrogenated solution; 3) contacting the second stream of the hydrogenated solution and the regenerated hydrogenated solution with an oxygen-containing gas for oxidation reaction to obtain an oxidized solution; and 4) carrying out extraction separation on the oxidized solution to obtain an extract liquor containing hydrogen peroxide and a raffinate, and recycling the raffinate.
