液晶界面物理效应研究及进展

液晶表面和与它接触的固体表面的相互作用，作为边界条件对液晶显示起着重要的控制作用，并影响着液晶表现出的各种物理效应．液晶表面和界面科学一直是液晶物理学研究的重要领域．这一领域内一个重要的课题是，从物理机理出发寻找正确反映界面作用规律的数学物理方程，以便完善发展液晶界面理论，指导界面诱导技术．文章就这一研究领域已取得的成果、未解决的问题、当前研究的热点(一级转变和挠曲电效应)及目前有争议的问题(表面弹性项是否存在等)进行了介绍。

Studies of the interfacial physical effects of liquid crystal cells

The interaction between a liquid cr ys tal and the solid surface it is in contact with controls the display and influen ces the physical effects of the liquid crystal. The surface and interface behavi or of liquid crystals is an important field of research, in which a major task i s to find appropriate mathematical and physical equations to describe the liquid crystal\|solid interaction. Development of the theory will help to improve surf ace inducement technology. The achievements obtained, problems still unsolved, c urrent points of interest (such as the first order transitions and flexoelectric effect) and controversial issues (whether the surface elasticity term exists or not) are reviewed.
