这项工作提出了一个分析,确定了两个突出的机制,管理螺旋解旋剪切双折射液晶。在自由表面取向的存在下,螺旋展开通过行进取向波的螺距膨胀进行,并且在固定表面取向的存在下,螺旋展开通过弹性边界层的压缩进行。(C)1996年美国物理学会。
This work presents an analysis that identifies the two prominent mechanisms that govern the helix uncoiling of sheared cholesteric liquid crystals. In the presence of free surface orientation helix uncoiling proceed by pitch expansion of traveling orientational waves, and in the presence of fixed surface orientation helix uncoiling proceeds via compression of elastic boundary layers.
