Abstract: A dynamic simulation test platform for ultra-high-speed evacuated tube magnetic levitation (maglev) transportation includes an evacuated tube having a transition section and a vacuum section, a vacuum maintaining system, a motor supporting platform, and a model train. One end of the evacuated tube is provided with a first isolation door, and the other end is closed. A second isolation door is provided inside the evacuated tube. The vacuum maintaining system is connected to the transition section and the vacuum section. The motor supporting platform is provided in the evacuated tube and extends outside the transition section. The motor supporting platform is provided with a stator winding and a permanent-magnet track. A mover and a cryogenic dewar are provided at a bottom of the model train. The cryogenic dewar is provided with a superconducting bulk. A test method using the test platform is further provided.

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.

Abstract: Electrodes are used in fuel cells for generating electricity from a mixed feed, where the mixed feed comprises a fuel portion and an oxidation portion. Fuel cells incorporating the electrodes and a method of fabricating the fuel cells are described. In some embodiments, the electrodes comprise a barrier layer (120, 160) having first and second sides, permeable to one of the fuel portion and oxidant portions of the mixed feed, a catalyst layer (130, 150) formed on the first side of the barrier layer, and the reactant distribution layer (110, 170), formed on the second side of the barrier layer.
