摘要翻译：
聚合物薄膜脱湿实验证实了热噪声对流体流动特征时间尺度的强烈影响，并导致典型长度尺度的粗化的理论预测。通过实验和确定性模拟的比较，我们发现Navier-Stokes方程必须通过一个守恒体噪声项进行扩展才能得到毛细管波的观测谱。由于热涨落，对于大波器，谱由指数衰减变为幂律衰减。同时，非稳定扰动的典型波器的时间演化表现出确定性流体动力流动中所不存在的噪声引起的粗化。

英文摘要：
  Experiments on dewetting thin polymer films confirm the theoretical prediction that thermal noise can strongly influence characteristic time-scales of fluid flow and cause coarsening of typical length scales. Comparing the experiments with deterministic simulations, we show that the Navier-Stokes equation has to be extended by a conserved bulk noise term to accomplish the observed spectrum of capillary waves. Due to thermal fluctuations the spectrum changes from an exponential to a power law decay for large wavevectors. Also the time evolution of the typical wavevector of unstable perturbations exhibits noise induced coarsening that is absent in deterministic hydrodynamic flow.
