摘要
报导了一个受溶质Marangoni效应影响的液滴聚结的迟缓现象．采用示踪液滴法，对滴加在正戊醇水溶液表面、受自发界而流控制的硝基乙烷液滴的运动和存在状态进行了研究．结果显示，在一定体系中溶质Marangoni效应可导致液滴的悬浮态，并对液滴的聚并产生显著影响．由于界面状态的不同，示踪液滴也表现出完全不同的动力学特征．基于以上认识对液滴运动速率的计算得到了合理的结果．
A study of retardation of the coalescenec of a small liquid drop effected by the soluteMarallgoni effect is presellted. The state and movement of the nitroethane drop deposited on thesurface of an aqueous solution of 1-pentanol and affected by teh self-induced interfacial flux arestudied experimentally. It is shown that in certain system the solute Marangoni effect can inducea suspending state of the drop at the plane surface of an aqueous solution and effect appreciabllythe coalescence process of the drop ,and teh movement of the drop cansed by the interfacial fluxpresents quite different dymanic properties according to the different state of the drop at the surface. The calculation of the velocity of the drop motion on this consistent is in consistent with the experimental data.
