| Outline of Final Research Achievements |
The stabilization mechanism of atmospheric non thermal equilibrium three - dimensional plasma using “water dielectric multi layer electrode” were studied. Clarification of discharge mechanism were carried out by observation of discharge phenomena with control of temperature and electric property of water involved in the discharge electrode. In addition, application of this electric discharge to industrial technology was also studied. It was clearly observed that uniform discharge under non uniform electric field had been realized by the high-speed transfer of local discharge which was occurred by temperature rise of the water. The application of uniform plasma treatment to three-dimensional shaped agricultural products and industrial products is expected in the near future.

複雑な形状物を持つ農産物や工業製品へのプラズマ処理ができる立体形状を持つ大気圧非平衡プラズマの生成が可能であることは，既存の大気圧非平衡プラズマの研究と比較しても，非常に独創的である．その発生メカニズムの解明は理学，工学の両面から極めて有意義である．この放電のメカニズムを解明することで，形状やサイズの為にプラズマ利用が出来なかった，農業・工業などの新しい分野でのプラズマ応用の展開が期待できる．
