本文介绍了一种用中子或光小角散射技术研究泊里叶剪切流下流体结构的新装置。该设计的重要特点包括低样品量、高达5000 s（-1）的面积平均剪切速率、10-125 ℃范围内的精确温度控制以及研究流动诱导排列现象发展的能力。小角中子散射数据给出了两个示例系统：良好表征的表面活性剂系统C（16）E（6）/D2 O，用于对比Poiquillille和Couette流的影响，和嵌段共聚物Synperonic P-85/D2 O系统。(C)1996年美国物理学会。
A new apparatus to investigate the structure of fluids under Poiseuille shear flow using small-angle neutron or light scattering techniques is described. Important features of the design include low sample volumes, area average shear rates of up to 5000 s(-1), accurate temperature control over the range of 10-125 degrees C, and the ability to study the development of flow-induced alignment phenomena. Small-angle neutron scattering data are presented for two example systems: the well-characterized surfactant system C(16)E(6)/D2O, used to contrast the effects of Poiseuille and Couette flow, and the block copolymer Synperonic P-85/D2O system.
