用高速数字摄影研究了初始平面钴/铝放热多层箔中的热分解反应。反应的实时观测表明，非稳态（类自旋）反应的传播导致形成高度周期性的表面形貌，其长度尺度从1 μm到1 mm。传播类自旋反应的特征和相应的反应箔形貌取决于多层箔的双层厚度。
Propagating reactions in initially planar cobalt/aluminum exothermic multilayer foils have been investigated using high-speed digital photography. Real-time observations of reactions indicate that unsteady (spinlike) reaction propagation leads to the formation of highly periodic surface morphologies with length scales ranging from 1 μm to 1 mm. The characteristics of propagating spinlike reactions and corresponding reacted foil morphologies depend on the bilayer thickness of multilayer foils.
