| 摘 要： | 通过对水下排气气泡的受力分析，建立了一个工程实用的水下气泡运动数学模型．通过对模型的求解，获得水下气泡运动特性，发现气泡在脱离其出口后，在很短时间内即向上运动，且铅垂方向速度很快达到一定值，但有较小波动，水平各向速度很快趋于零。

| Abstract: | A practical mathematics modeling for bubble movement in the field of engineering was built by analyzing apparent forces of exhaust bubble in water. The bubble movement characteristics were obtained by solving the equation. The results showed that the bubbles moved upwards in a little time after deviating exhaust port; the upright orientation velocity achieved a less fluctuant fixed value; the level orientation velocity achieved zero. |
