| 摘 要： | 通过对水下气泡的受力分析,建立气泡在水中运动的微分方程,通过数值方法进行简化求解,得出用水深表示速度的ω(h)解析关系式,用以描述气泡运动包括加速段的整个过程.气泡急剧加速上升阶段很短,与直径有关;上升的最终速度与气泡的直径有关,与水深无关;接近恒速阶段的起始速度与水深有密切关系.

| Abstract: | Through the analysis of the air bubble stress under water,the differential equation of air bubble movement in water was established.The simplification was carried out through the value method,and the analytic equation of ω(h),with water depth experssing speed,was put forward to describe the whole process of air babble movement including the acceleration phase.The severe acceleration phase is short which is conneted with diameter,and the final uplifted speed is also connected with dia,but has nothing to do with water depth which is contrary to the start speed of approximate constant phase. |
