我们证明了一个一阶各向同性的液晶相变，可以成功地在广义Landau-de Gennes理论通过选择一个适当的弹性常数的组合建模。本文所建立的模型的数值模拟定性地再现了实验观察到的配置，包括界面和拓扑缺陷的双相。
We demonstrate that a first order isotropic-to-nematic phase transition in liquid crystals can be succesfully modeled within the generalized Landau-de Gennes theory by selecting an appropriate combination of elastic constants. The numerical simulations of the model established in this paper qualitatively reproduce the experimentally observed configurations that include interfaces and topological defects in the nematic phase.
