Color adjusting apparatus and method for a light source. A tensile specimen measuring method is also disclosed. According to the invention, the electrode path is coated with catalytic activating particles made from one or more non-oxidic inorganic metal compounds, which are reacted to form the corresponding metal oxides under gas development. The progressive separation of the load flanks is achieved by progressively changing the pitch of the load flank of the pin andor box thread to vary the thread width. The controller dynamically connects a plurality of telephone terminals using the same codec to a media server via the distribution server.
