Using computer simulation technique, Ozone-zero phenomena and Recovery phenomena have been clarified. Ozone-zero phenomena occur in three steps. 1. Intense sputtering of the dielectric surfaces decreases secondary electron emission 2. Decrease of secondary electron emission induces high gas(oxygen molecules) temperature region in the vicinity of the dielectrics. 3. Ozone generation decreases by the low gas density (=high temperature). Recovery process is induced by the nitrogen atoms which is dissociated from the nitrogen or nitrogen monoxide. Nitrogen atoms increases oxygen atoms by reacting with oxygen molecules. Increase of oxygen atoms compensates the decrease of oxygen molecules some degree. In the condition of uniform gas temperature, unique self-organized plasmas which could generate ozone efficiently, are formed.
