Abstract: An emulated card switching method, electronic device, and communication system are provided. The method includes sending first information to an near field communication (NFC) card reader which determines a first protocol based on the first information and a protocol supported by the NFC card reader, and performs a service process of the first protocol with the electronic device, if no identification information is obtained, modifying protocol information of a first emulated card from the first information to second information, sending the second information to the NFC card reader which obtains the second information from the electronic device, determines a second protocol based on the second information and the protocol supported by the NFC card reader, and performs a service process of the second protocol with the electronic device, and if identification information is obtained, switching the first emulated card to a second emulated card corresponding to the identification information.

Abstract: A heat dissipation system for a high-speed train running in a low-vacuum tube is provided. Component groups that provide power and resistance for the movement and stop of a train are provided at a periphery, close to the train, in a low-vacuum tube. The component group is provided with a group A cooling assembly. The group A cooling assembly includes a group A cooling-type heat exchanger and/or a group A nozzle assembly attached to the back of the component group. Since the friction between the train running at high speed and the air in the low-vacuum tube and the operation of the key equipment in the low-vacuum tube will generate a lot of heat, the group A cooling assembly in the component group in the low-vacuum tube exchanges the heat with the air in the low-vacuum tube.

Abstract: Disclosed is a method of enhancing absorption spectral signals of a biological sample in a terahertz waveband in which the biological sample are embedded and supported with black silicon. In the method, the biological sample are filled between the surface micro-nano structures of a black silicon material and then freeze-dried. When the terahertz wave is incident upon the black silicon material, multiple reflections will occur between the micro-nano structures, so that the terahertz wave passes through the biological sample multiple times to increase the distance of interaction between the terahertz waves and the biological sample, allowing for enhanced absorption spectral signals of the biological sample and improved identifiability of the biological sample. The method is simple and easy to implement and low in cost.

Abstract: Embodiments of the present disclosure disclose an access processing method. The access processing method includes when it is detected that a target network access point cannot access a network in previous network access detection that is closest to a current moment, obtaining network access information of the target network access point before the previous network access detection; analyzing the network access information to determine whether the target network access point has a network access capability; and if the target network access point has the network access capability, automatically accessing the target network access point, and detecting whether the target network access point can currently access the network. Embodiments of the present disclosure further disclose an access processing apparatus. By using the present disclosure, filtering out, because of erroneous determining, a target network access point that can access a network is avoided, and accuracy of network access detection is improved.
