In many ways aerobics, aerobics in different ways aeration efficiency is not high background, we will Venturi vacuum suction principle and fluid power ultrasonic sound design principles combined to form a hydrodynamic ultrasonic oxygen apparatus. This paper, focusing reed whistle and hydrodynamic ultrasonic nozzle oxygen apparatus, in different sizes fit to work out their different aeration efficiency of water aerobics to elect the best fit size. At the same time, the effects of the intake air amount of dissolved oxygen in the water and oxygen after passing through the water with time trends. Following results were obtained:(1) optimize the size of the device. The experiment produced three different reed length, thickness and height of the nozzle combination of a lot of tests. Finally, the results obtained are:reed length of 43mm, reed thickness 1.0mm,9mm height of the nozzle when the current water temperature, dissolved oxygen which can be saturated or supersaturated.(2) means the intake air quantity of water aerobic effect. Intake air at 2L/min, there has been a sharp increase in the amount of dissolved oxygen, the oxygen absorption of water at this time is best. When the intake air amount from about 2-10L/min, the rate of increase in the amount of dissolved oxygen becomes smaller, the effect of oxygen slowly. After lOL/min, substantially increasing the amount of dissolved oxygen, to form a stable constant value.(3) Test the water with the trend of time. The trial in the amount of oxygen dissolved oxygen after the oxygen content will continue to increase in 2 hours,2 hours maximum; after 2 hours, dissolved oxygen will decline sharply; after 6 hours, the amount of dissolved oxygen in the rate of decline smaller; last 20 hours, when the amount of dissolved oxygen tends to remain stable state.
