We optimized the performance of the PSCT valve by adjusting the cholesteric pitch, the polymer concentration and polymerization condition.
通过调节胆甾相液晶的螺矩、聚合物的浓度和聚合反应条件，我们能使PSCT光阀性能最优化。
A cholesteric-nematic transition can be induced by a magnetic field which is normal to the pitch of the cholesteric liquid crystals.
垂直于液晶胆甾相加磁场可以引起胆甾相向列相转变，基于分子场理论解释了这一现象。
The molecular structure of cholesteric liquid crystals is spiral, and its pitch can be modified reversibly by heat or cool, irradiation, and electric field.
胆甾相液晶分子呈螺旋结构，并且其螺距可以用加热冷却、光照和施加电场的方法进行可逆调整。
