摘要翻译：
通过布朗动力学模拟研究了剪切流作用下胶体悬浮液的有序-无序转变。我们用结构因子随时间变化的最大值的统计性质来描述这种转变。我们发现它的功率谱仅在有序相中表现出幂律行为。在大于剪切速率的频率下，幂律指数约为-2，而在较低频率下，功率谱呈现$1/f$型涨落。

英文摘要：
  We study the order-disorder transition in colloidal suspensions under shear flow by performing Brownian dynamics simulations. We characterize the transition in terms of a statistical property of time-dependent maximum value of the structure factor. We find that its power spectrum exhibits the power-law behaviour only in the ordered phase. The power-law exponent is approximately -2 at frequencies greater than the magnitude of the shear rate, while the power spectrum exhibits the $1 / f$-type fluctuations in the lower frequency regime.
