The underground magnetic suspension ultra-high-speed train vacuum tunnel is located at the position 50-100 m underground and comprises a plurality of sections of vacuum pipelines and station channels which are arranged at intervals, and rails are laid in the vacuum pipelines and the station pipelines; a cabin door group is arranged in the station channel and comprises four cabin doors which are arranged in sequence and can be opened and closed, namely a cabin door I, a cabin door II, a cabin door III and a cabin door IV, a waiting cabin I is arranged between the cabin door I and the cabin door II, a waiting cabin II is arranged between the cabin door III and the cabin door IV, a passenger getting-on and getting-off cabin is arranged between the cabin door II and the cabin door III, and an in-out elevator is arranged between the passenger getting-on and getting-off cabin and the ground; a plurality of vacuumizing openings and air supply openings are formed in the vacuum pipeline, the waiting bin I and the waiting bin II, air supply openings are formed in the getting-on and getting-off bin, each vacuumizing opening is provided with an evacuator, and each air supply opening is provided with an air feeder; and during normal passing, the air pressure in the vacuum pipeline is 10% of one standard atmospheric pressure. The technical scheme does not occupy the ground surface area and prevents noise from disturbing residents.

Methods, systems, and devices are described for wireless communication. A base station, which can include at least two transmission reception points (TRPs) adjacent to a high speed train (HST), can transmit, to a user equipment (UE) on the HST, an indication of a quasi co-location (QCL) relationship, the indication indicating a relationship between a plurality of tracking reference signals (TRSs) and a demodulation reference signal (DMRS) of a data channel. The plurality of TRSs can include a first TRS and a second TRS. The UE can receive, from a first TRP, the first TRS associated with a time occasion of the data channel and receive, from a second TRP, the second TRS associated with the time occasion of the data channel. The UE can perform, based on the indication of the QCL relationship, a channel estimation procedure for the data channel based on the DMRS, the received first TRS, and the received second TRS.

1. The name of the design product: Oxygen cylinder clamping stabilizer (for high-speed rail). 2. The use of the design product: used for stabilizing oxygen cylinders in high-speed rail transportation to prevent tilting and collision. 3. The design points of the design product: in shape. 4. The picture or photo that best indicates the design points: perspective view.

The invention discloses a flow guide structure for pneumatic resistance reduction of a high-speed motor train unit. The flow guide structure is integrally formed on the side lower portion of a bogie apron board and / or an equipment compartment apron board and extends in the length direction of the corresponding apron board. The flow guide structure is used for actively inducing airflow to generate a guide effect at the position; the change of the flow direction of the airflow is used for inhibiting the downward rolling of the main airflow on the vehicle side to the bogie area below the vehicle, and / or reducing the generation and the scale of disordered vortexes in a bogie cabin; the flow guide structure comprises a flow guide main body extending outwards, the two ends of the flow guide main body are smoothly connected with the corresponding apron boards through wedge-shaped sections, the connection roots of the flow guide main body and the apron boards are in transition through arc surfaces, and the arc surfaces are bent towards the inner side of the bottom of the motor train unit. According to the flow guide structure, a guide airflow is induced to be generated when a train runs through a specific geometric shape, the two ends of the structure adopt wedge-shaped design, and the resistance introduced by the structure is reduced with a high slenderness ratio.
