Abstract
Summary form only given. In this paper, the commercial graphite fibers, which has a diameter of about 20 mum is used as cathode in field emission. We can achieve notable emission current by using the graphite fiber disposed high voltage. Owing to the existence of fluctuation of emission current when direct voltage is applied. In this paper the high frequent AC voltage is used to avoid the twinkle phenomenon of the emission current (shown as a picture on fluorescence screen). And stable emission current has been attained. As a result, some applications can be achieved by this way
