A method for making a ceiling fan blade comprises the steps of cutting, inside drying, surface wetting, surface spraying, and surface forming. The first electrode portion includes, at least in part, an antenna portion having an antenna function of distributing the carrier generated by the irradiation with the excitation light in a direction crossing an application direction of the electric field. The relay may receive turbo coded signals from the UEs. In the drawing process, the pressure applied on the marking point is directly controlled by hand. A locking mechanism is disposed within the body for locking the tubes in either the extended state or the retracted state. They may optionally be used in a combination with palladium or platinum.
