Water purification of the ocean environment and the revival of the ocean creature by using micro bubble technology were investigated. The results of the experiments are as the following.(1)The generating devices of micro bubble were developed, and the diameter of the bubbles and rising velocity were measured. Further, it was examined about the physical mechanism of a micro-bubble to shrink.(2)The process of generation of micro bubble was taken by high-speed camera. It was cleared that micro bubbles generated at a rotating velocity of about a 400 rps. The physical and chemical characteristics of the micro bubble were examined and the characteristics was called the effect on size of the micro bubble.(3)The characteristic on physiological activity of micro bubble for ocean creature and human body was found. The blood flow on the surface of skin of the creature with providing micro bubbles was promoted two times higher than the usual flow.(4)The results of micro bubble technology for oyster culture, scallop culture and pearl culture were discussed systematically. Based on the above, the possibility of the water environment revival technology by using micro bubble was explained.

研究了利用微气泡技术净化海洋环境水体和复活海洋生物。实验结果如下。（1）研制了微气泡发生装置，并对气泡的直径和上升速度进行了测量。此外，还研究了微泡收缩的物理机制。（2）用高速摄像机拍摄了微气泡的生成过程。已经清楚的是，在约400rps的旋转速度下产生微气泡。考察了微气泡的物理和化学特性，称之为对微气泡尺寸的影响。（3）发现了微泡对海洋生物和人体的生理活动特性，微泡对生物皮肤表面的血流量有促进作用，比正常情况下的血流量增加了2倍。（4）系统论述了微气泡技术在牡蛎养殖、扇贝养殖和珍珠养殖中的应用效果。在此基础上，阐述了利用微气泡进行水环境修复的可能性。
