Abstract: Provided is a use of an aggregation-induced emission compound in dispersion detecting of nanoparticles. The dispersion detecting of nanoparticles includes modifying the aggregation-induced emission compound on the surfaces of the nanoparticles to obtain a modified nanoparticles solution. The dispersion detecting of nanoparticles includes exciting the modified nanoparticles solution and determining the dispersion of the nanoparticles by the luminescence state of the solution.

Abstract: Embodiments of the present invention disclose a display screen control method and apparatus, and a terminal. The method in the embodiments of the present invention includes obtaining a height difference and an acceleration that are generated when a terminal moves from an initial position to a target position and determining, according to the height difference and the acceleration, whether a first predetermined movement is satisfied. The method also includes when the first predetermined movement is satisfied, triggering the terminal to turn on a display screen.

Abstract: This disclosure relates to methods for adjusting network transmission service levels, data terminals, and network servers. The method for adjusting a network transmission service level, used in a data terminal, comprises: obtaining data to be transmitted; inserting the data into specified queues or assigning priorities to the data according to one or more data characteristics selected from importance, instantaneity, data resources, and data types; transmitting a transmission service request to a network server, wherein the transmission service request includes information about the network transmission service level requested and corresponding network configuration parameters; and using the network transmission service provided by the network server according to the transmission service request to transmit the data in queues or the data whose priorities correspond to the network transmission service level provided.
