2014 .研究了动态光散射作为稳定线性剪切系统波动探测的方法。为计算由独立粒子或低剪切率波动组成的密集系统的强度相关函数，提出了几种近似方法。在此极限下，强度相关函数在结构上与平衡强度相关函数相似；但是，信号与背景因子的相关性依赖于相关时间。通过测量布朗粒子受剪切作用的稀溶液的强度相关函数，对结果进行了实验验证。讨论了用动态光散射作为剪切系统波动探测的可行性。J.体质42 (1981)929-936
2014 Dynamic light scattering as a probe of fluctuations for systems undergoing steady linear shear is examined. Several approximations are made to calculate the intensity correlation function for a dense system of independent particles or fluctuations at low rates of shear. In this limit the intensity correlation function is similar in structure to the equilibrium intensity correlation function ; however, the signal to background factor becomes correlation time dependent. The result is tested experimentally by measuring the intensity correlation function for a dilute solution of Brownian particles undergoing shear. The feasibility of using dynamic light scattering as a probe of fluctuations in sheared systems is discussed. J. Physique 42 (1981) 929-936 JUILLET 1981,
