Abstract: A method for exchanging information between in-vehicle terminals, and an in-vehicle terminal is provided. The method includes a first in-vehicle terminal that triggers, by sending a broadcast message, at least one surrounding second in-vehicle terminal to establish a first relationship with the first in-vehicle terminal, and establishes a second relationship with at least one third in-vehicle terminal. The first in-vehicle terminal separately exchanges information about a correspondence type with the at least one second or third in-vehicle terminal so that more vehicles can intelligently exchange in-vehicle information, and exchange different information with different in-vehicle terminals. This can properly protect privacy information.

Abstract: The present invention provides a protein fragment for fusion expression of ion channel protein and transport protein. The protein fragment is a Bril protein fragment or a T4L protein fragment. Also provided is a method for preparing a fusion protein by inserting a Brit protein fragment or T4L protein fragment into the N-terminal, C-terminal or intramembrane loop region of the ion channel protein and transport protein so as to improve its, in-vitro stability and crystallizability.

Abstract: A photographing method, including receiving a first instruction generated when a user executes a first operation on a mobile terminal, determining, according to the first instruction, whether the first operation matches a first preset operation, and powering on hardware used for photographing in response to the first operation matching the first preset operation, and preloading a camera application resource. The method further includes receiving a second instruction generated when a user executes a second operation on the mobile terminal, determining, according to the second instruction, whether the second operation matches a second preset operation, and executing a photographing action in response to the second operation matching the second preset operation. A mobile terminal is also disclosed.
