摘要自支撑近晶气泡由纳米到微米厚度的高度有序膜组成。它们的半径可以达到几厘米。类似于肥皂泡，它们可以通过对平面自由悬浮的近晶薄膜施加侧压力而产生。我们描述了这些物体的光学性质以及从透射式图像中确定膜厚度的方法。简要讨论了气泡表面空洞(层数减少的区域)的生长和运动的动力学。
Abstract Self-supporting smectic bubbles consist of highly ordered membranes of nanometer to micrometer thickness. They can reach radii of several centimeters. Analogous to soap bubbles, they can be generated by excerting lateral pressure on a planar freely suspended smectic film. We describe the optical properties of these objects and the determination of the membrane thickness from transmission images. The dynamics of the growth and motion of holes (regions of reduced number of layers) on the bubble surface is briefly discussed.
