Corrosion inhibitors and methods for inhibiting or reducing corrosion of metallic surfaces are provided. The actuator driver is accommodated in the casing and drives the actuator. The resource blocks each correspond to a specific time and frequency range and each consist of a number of resource elements which each correspond to a specific time and frequency range. Injecting burst errors at the system level provides a network simulation that more realistically reflects the effects of burst errors on network performance. After depositing a rapid-thermal chemical vapor deposition dielectric layer that covers both the substrate and the gate, a spacer on either side of the gate is finally formed by etching back the RTCVD dielectric layer.
