在两个不相混溶的液体界面上,当体系从不平衡状态回到平衡状态时,产生界面流体不稳定现象,发生运动。体系中一般含有带电质点,其中之一具有表面活性。这种现象可归因于Marangoni效应。众所周知,此效应是由于通过界面的质量迁移产生界面张力梯度,因而引起一股界面流。 In the two immiscible liquid interface, when the system returns from the unbalanced state to equilibrium, the interface fluid instability occurs, the movement occurs. The system generally contains charged particles, one of which has surface activity. This phenomenon can be attributed to the Marangoni effect. It is well-known that this effect is due to the interfacial tension gradient created by the mass transfer of the interface, thus causing an interface flow.
