| Research Abstract |
The purpose of this study is to control the disappearance interval of bubble caused by gas diffusion out to bubble. The effectiveness of single bubble generation by laser, long existence of multi-bubbles in closed area, and the suppression of gas diffusion with additives on the surface of bubble were confirmed in this study.
