本文讨论了剪切有序胶态分散体的光衍射问题，用散射功率分布I（I）沿着六角层布喇格棒分布。对于电荷稳定的分散体，使用光散射强度的角度依赖性来确定I（I），由此可以得出关于层的相互配准、堆叠顺序和结晶动力学的结论。对于所研究的系统从随机密排六角层的结构过渡到故障孪晶费确定。
Light diffraction from shear ordered colloidal dispersions is discussed in terms of the scattering power distribution I(I) along Bragg rods of hexagonal layers. For a charge stabilized dispersion the angle dependence of the light scattering intensity is used to determine I(l), from which conclusions on the mutual registration of the layers, the stacking order, and the kinetics of crystallization can be drawn. For the system under study a structural transition from random close-packed hexagonal layers to faulted twinned fee is identified.
