The method includes: A terminal establishes a wireless connection to another terminal; in addition, the terminal establishes a USB connection to the another terminal; then, the terminal can display a first interface, where the first interface includes at least one piece of candidate data; a user may select to-be-transmitted data from the at least one piece of candidate data after performing a first input on the first interface; and the terminal may send the to-be-transmitted data to the another terminal through the wireless connection and the USB connection after the user performs a second input on the first interface.

Abstract: A piston limiting structure, including: a cylinder, a piston, and a flange provided with a limiting piece, the cylinder has a piston hole perpendicular to an axial direction of the cylinder and penetrating through the cylinder, and a projection of the piston hole in a penetrating direction is circular. The piston is disposed in the piston hole in a form-fit manner and is slid in the piston hole in a reciprocating manner. A side wall of the piston is provided with a thrust groove, a bottom surface of the thrust groove forms a thrust surface on the side wall of the piston, and the thrust groove does not penetrate through two ends of the side wall of the piston along an axial length of the piston. The limiting piece abuts against the thrust surface.

Abstract: A first apparatus sends a first random number to a second apparatus, where a vehicle carries the first apparatus and a first set. The second apparatus belongs to the first set. The first set further includes a third apparatus. The first apparatus communicates with the third apparatus using the second apparatus. The first apparatus receives a first message from the second apparatus. The first message includes first verification information to perform identity verification on the second apparatus. The first verification information is based on identity information of the second apparatus and the first random number. The first apparatus determines, based on the first verification information and the first random number, that the identity verification on the second apparatus has succeeded.

Abstract: A method for processing a plurality of queries is provided according to embodiments of the present disclosure. In this method, based on a plurality of queries and an execution plan for the plurality of quires, a plurality of record identification (ID) numbers can be stored into a pool in a numerical order. Each of the plurality of record ID numbers can identify a data record in a database. Then, the execution plan can be performed to batch a plurality of data records corresponding to the plurality of record ID numbers in the database based on a distribution of the plurality of record ID numbers in the pool.

Abstract: A device and a method for reducing wind resistance power of a large geotechnical centrifuge are provided. A semicircular tube cylindrical cooling device is provided between an internal side of a high-speed rotor system and a cylindrical shell. A serpentine top semicircular tube cooling plate is provided right above a hanging basket, and return helium gas inlet holes are provided at a center of the top semicircular tube cooling plate. A helium gas in a helium gas storage tank passes through helium gas outlets on the helium gas inlet pipes, and enters a centrifuge chamber from a bottom sealing plate. The helium gas is used to replace air in the centrifuge chamber to reduce the wind resistance power and corresponding energy consumption. No vacuuming is required, so sealing requirements are lower. Heat dissipation equipment is placed inside the centrifuge chamber, and a helium gas circulation wind duct is added.

A semicircular tube cylindrical cooling device is installed between an internal side of a high-speed rotor system and a cylindrical shell. A serpentine top semicircular tube cooling plate is provided right above a hanging basket, and return helium gas inlet holes are opened at a center of the top semicircular tube cooling plate.

The helium gas is used to replace air in the centrifuge chamber to reduce the wind resistance power and corresponding energy consumption. No vacuuming is required, so sealing requirements are lower. Heat dissipation equipment is placed inside the centrifuge chamber, and a helium gas circulation wind duct is added to improve heat exchange coefficient and heat dissipation effect.

Abstract: A method for generating a frequency warping function comprising preparing the training speech of a source and a target speaker; performing frame alignment on the training speech of the speakers; selecting aligned frames from the frame-aligned training speech of the speakers; extracting corresponding sets of formant parameters from the selected aligned frames; and generating a frequency warping function based on the corresponding sets of formant parameters. The step of selecting aligned frames preferably selects a pair of aligned frames in the middle of the same or similar frame-aligned phonemes with the same or similar contexts in the speech of the source speaker and target speaker. The step of generating a frequency warping function preferably uses the various pairs of corresponding formant parameters in the corresponding sets of formant parameters as key positions in a piecewise linear frequency warping function to generate the frequency warping function.
