The pump body assembly includes a piston, a shaft, a piston sheath, and a cylinder. The shaft drives the piston to rotate and reciprocate within the piston sheath while rotating. The piston sheath is located in the cylinder, and a compression chamber is defined between an outer circumferential wall of the piston and an inner wall of the cylinder. A pressure relief recess is defined in the outer circumferential wall of the piston or the inner wall of the cylinder at a position corresponding to the compression chamber.

Abstract: The present application relates to a data transmission method, a system, a computer device, and a storage medium. Since a target extension unit is an extension unit connected to a service distal end unit of a matching user equipment set, when data is transmitted between a host unit and a user equipment, data only needs to be transmitted to a service distal end unit group connected to the target extension unit by means of the target extension unit, and data transmission is not needed to be performed with all distal end unit groups, so that a fronthaul bandwidth between the host unit and the extension unit/distal end unit is greatly decreased, thereby reducing design costs of a baseband of the host unit. In addition, the host unit pre-matches the user equipment which can share the same time frequency resource. Therefore, the same time frequency resource only needs to be allocated to the matching user equipment set, which greatly improves the utilization rate of an air interface resource.

Abstract: An apparatus for applying an electron beam to a subdermal tumor generates a pulsed electron beam that is collimated to a diameter of less than 1 mm and less than 10 millimeter-milliradiant transverse emittance. A biopsy needle having an interior diameter less than 2 mm and length between 1 cm and 100 cm is inserted through the skin to the tumor, and the electron beam is electromagnetically directed through the needle, so as to reach the tumor without irradiating intervening normal tissue and with minimal irradiation of surrounding normal tissue. The electron pulsing rate can be in the S-band or Q-band, the beam energy can be between 1 Mev and 6 MeV, and/or the beam brightness can be less than 10 mm·mrad. A distal end of the biopsy needle can include an electron-permeable vacuum barrier, and the apparatus can be evacuated to less than 10?8 Torr.
