博士 === 國立臺灣大學 === 物理學系 === 85 === In this thesis, we use a fast line scan CCD camera to study the bursting of soap films and soap bubbles. In the case of soap films, we can clearly observe the aureole formation and shock wave propagation. The time dependence of the shape and velocity of the aureole are obtained for the first time. We found that during bursting the surfactant monolayer in the aureole is highly compressed and behaves like a rigid film. We also calculate the surfactant compression ratio with shock wave theory. New phenomena of detachments of the aureole from the bursting film are also observed. In the case of the soap bubbles, we burst the films of different geometry to understand why the aureole is absent in the bursting of the soap bubbles.
