在扭剪流动装置中研究了两种双折射液晶。向列相是MBBA（负昼夜各向异性）和5CB（正昼夜各向异性）。除了靠近表面的两个边界层外，指向矢在剪切中与流动方向的法线成一定的角度θn。从理论和实验两方面研究了电场对气流排列角和边界层大小的影响。
Abstract Two nematic liquid crystals are studied in a torsional shear flow apparatus. The nematics are MBBA (neg.diel.anisotropy) and 5CB (pos.diel.anisotropy). The director align in the shear at a certain angle θn to the normal to the flow direction, except at two boundary layers near the surfaces. The influence of an electric field on the flow alignment angle and on the size of the boundary layers is studied both theoretically and experimentally.
