我们报告了与肺功能有关的某些压缩脂质单层的随机崩溃中迄今为止未被认识的合作行为。这种协同性来自对使用荧光显微镜和数字图像分析捕获的塌陷事件的统计分析。塌陷事件涉及微米级的单层折叠，但每个事件都会产生宏观的层抖动。合作崩溃因其时间上的急剧性和空间上的广泛性而引人注目。
We report hitherto unrecognized cooperative behavior in the stochastic collapse of certain compressed lipid monolayers implicated in pulmonary function. The cooperativity emerges from a statistical analysis of the collapse events captured using fluorescence microscopy and digital image analysis. The collapse events involve folding of the monolayer on a micron scale, yet each event produces a macroscopic jerk of the layer. The cooperative collapse is striking for its temporal sharpness and large spatial extent.
