| 摘 要： | 对单个气泡传质的近界面浓度场影响因素进行了实验和理论研究．实时激光全息干涉法测量结果表明，运动气泡近界面浓度是一个定态值，受流速、泡径、温度等因素影响显著；假设该传质过程达到局部平衡，进行热力学分析，得到的结论与实验结果一致．在实验测量结果的基础上，对单个O_2气泡在乙醇中吸收时的传质近界面浓度场进行了数值模拟，取得了良好的结果．

| Abstract: | In order to afford an insight into the problem of bubble mass transfer,this paper experimentally and theoretically deals with the effective factors of near-interfacial mass transfer of a single bubble.The micro real-time holographic interference results showed that near-interfacial concentration is a stable value of dynamic mass transfer.It was affected by relative velocity,bubble dianmeter,temperature,pressure,etc.The thermodynamic analysis of the bubble mass transfer got the same result as experiment.Nunerical simulation of the near-interfacial concentration field of a single CO_2 bubble absorbed in alcohol was made. |

| Keywords: | real time holographic interference thermodynamic analysis near-interfacial concentration field simulation single bubble |
