A component-based framework includes system services and component integration interfaces that provide a run-time environment for component-based server application in which server application components have control over the duration of their state independent of client action. The system includes an accommodating space accommodating a transmission mechanism, a blower fan rotatably driven by a crankshaft, and a cooling air channel extending between a combustion chamber and the valve chamber disposed above the combustion chamber. A second variable associated with a second time duration may be determined by the receiver of the data packet. The temperature controlling module is provided for controlling the surface temperature of the substrate, such that the temperature of the substrate and the micro-droplets is balanced, and then the surface flatness of the film plated by micro-droplets is improved.
