This effect has been discussed in terms of the cage theory of liquids by bayhis and rees . 贝丽斯与雷斯曾用液体的笼蔽理论讨论过这一效应。
Kinetic theory of liquids 液体的分子运动论
Due to the nonlinearity and complexity of many - body problems , the molecular statistical theory of liquid crystals has not been perfect as yet 液晶的分子统计理论,由于多体问题所涉及到的非线性和复杂性,至今远远没有得到完善的答案。
Based on the elastic theory of liquid crystal and variation theory , the effect was studied , and the differential equation and boundary condition about the director of liquid crystal were obtained 基于液晶弹性理论研究了这一效应,通过变分理论得到了液晶指向矢满足的微分方程及边界条件。
Fourthly , with the finite element program , the author analyzes the relationship between the load magnitude or frequency and range of breakage or pore pressure . this can provide appropriate parameters for the method of vibrating grouting . fifthly , adopting the compressible porous medium , the author adduced dynamic theory of liquid saturated porous medium to analyze the displacement and force in the sand when there is dynamic load below the earth surface 基于连续介质力学的混合物理论建立的多孔介质理论和动力控制方程,假设砂土满足各向同性并处于弹性小应变状态,竖向振动力将在饱和砂土内部产生三种波,分析了这些波的弥散曲线和特征衰减曲线,从波传播的角度,研究了振动力参数和土性参数对振动范围的影响。
In the first chapter , the fundamental concepts on the theory of liquid crystal are simply narrated , the definition about the flexoelectric effect and the expression on the polarization energy induced by the flexoelectric effect are expounded in detail , the research progress to the flexoelectric effect is illustrates in summary , then the work principle of liquid crystal display is expanded 本文第一章简单叙述了液晶理论中的基本概念,详细阐明了什么是挠曲电效应以及由挠曲电效应引起的极化能量表达式的形式,对挠曲电效应的研究进展作了扼要说明,紧接着就液晶显示器的工作原理进行了阐述。
