摘要：

In this article we present the results of computer simulations on a simple oil/water/surfactant system. These simulations show surprisingly rich structural detail. A monolayer of surfactants is formed at the oil/water interface, and in the water phase spontaneous micellization has occurred. A depletion layer, containing only water, separates the monolayer from the micelles. The density profile of the micelles oscillates close to the interface. It is suggested that these oscillations provide an explanation of the results of neutron reflectivity experiments on water-surfactant systems. Furthermore, the structure of the formed micelles has been studied in detail and compared with experimental data and some theories.
