本文研究了胶体颗粒在高浓度悬浮液中对稳定剪切速率的应力响应。我们发现，在一个小范围的浓度和剪切速率，应力表现出巨大的波动。这些波动的幅度服从幂律行为，直到出现新的流动分支，导致表现出明确定义的周期性的高幅度波动。
We study the stress response to a steady imposed shear rate in a concentrated suspension of colloidal particles. We show that, in a small range of concentrations and shear rates, stress exhibits giant fluctuations. The amplitude of these fluctuations obeys a power-law behavior, up to the apparition of a new branch of flow, leading to an excess of high amplitude fluctuations which exhibit a well-defined periodicity.
