Embodiments of the present invention provide a method, system and relevant apparatuses for supporting addressing by a user static Internet Protocol address in a Long Term Evolution system. A hub is fixed to a lower jig when a row of hub-side balls is disposed and an outer ring is disposed on an outer periphery of the hub and a row of inner ring-side balls and an inner ring are disposed. The spatial-acquisition apparatus is provided with a light-occluding slider that moves in front of the sample to block portions of diffuse scattering from the sample. By using this kind of apparatus and the process, the problem, that the metal foil easier wrinkles than paper does is overcome, and the substrate can close contact with the surface of the roller, the heat can be transferred more uniformly. The trigger unit has a trigger and a hammer, and the barrel unit includes a light emitting unit which emits a light bullet in response to generation of an impact by the hammer when a trigger operation is carried out by pulling the trigger. The method includes displaying a channel map showing a predetermined number of channels including a tuned broadcast channel if the channel adjusting item is selected through the user input part, and a channel setting information menu corresponding to one of the channels shown in the channel map.
