ABSTRACT On the basis of Landau-de Gennes theory, the fine structures of escaped concentric and ideal concentric configurations confined in nematic liquid crystal droplets were investigated. The escaped concentric configuration rather than the ideal concentric configuration appeared under the same conditions and parameters reported in Liq. Cryst., 45(1): 102 − 111, 2017. After increasing k 22 (twist elastic constant in Frank theory), the escaped concentric configuration transformed into the ideal concentric configuration. Within the ideal concentric configuration, we found an unexpecting order reconstruction occurred around the +1 line disclination, which has yet to be reported. In addition, the structural transitions within droplets of different radii were simulated. Graphical abstact

利用朗道-德热内斯理论研究向列型液晶液滴的同心构型

摘要 基于Landau-de Gennes 理论，研究了限制在向列液晶液滴中的逃逸同心和理想同心构型的精细结构。在 Liq 中报告的相同条件和参数下，出现了逃逸的同心构型而不是理想的同心构型。Cryst., 45(1): 102 − 111, 2017。在增加 k 22（弗兰克理论中的扭曲弹性常数）后，逃逸的同心构型转变为理想的同心构型。在理想的同心配置中，我们发现在 +1 线向错周围发生了意外的顺序重建，但尚未报告。此外，模拟了不同半径的液滴内的结构转变。图形摘要
