介绍了动态滴体积法测定油水界面动态界面张力的方法。时间尺度从大约0.5秒向上。该方法与E. Tornberg（J.Colloid Interface Sci.60，50（1977））。实验进行了非离子表面活性剂在水相中溶解，导致扩散控制（最终快速脱胶束）吸附动力学。对于溶解在油相中的胆固醇，吸附动力学不是由扩散也不是由吸附屏障，而是由界面处的重新取向过程来决定的。
The dynamic drop volume method is introduced for measuring dynamic interfacial tensions at the oil/water interface. The time scale is from about 0.5 s upward. This method is in agreement with the more static drop volume method of E. Tornberg (J. Colloid Interface Sci.60, 50 (1977)). Experiments were performed for nonionic surfactants solved in the aqueous phase, resulting in diffusion controlled (eventually with rapid demicellization) adsorption kinetics. For cholesterol dissolved in the oil phase, adsorption kinetics are not ruled by diffusion nor by an adsorption barrier but by a reorientation process at the interface.
