建立了一套基于剖面分析张力法（PAT）的气泡溶解过程界面特性研究装置。并对氮气泡和氦气泡进行了实验研究。实验结果表明，气泡溶解过程中表面张力降低，即界面处的平衡浓度状态被界面上的物质转移所打破，并由分子向液体中的转移速率决定。
A new setup for interfacial characteristics study during bubble dissolution based on Profile Analysis Tensiometry (PAT) is developed. And the investigations on nitrogen and helium bubble are carried out. The experimental results indicate the decrease of surface tension during bubble dissolution, which means the equilibrium concentration state at the interface is broken by the substance transfer across the interface, and is determined by the molecules transfer rate into the liquid.
