摘要/Abstract

摘要： 向列型液晶中的短程序有重要的物理效应。本文在格胞理论的基础上,用新的数值方法计算这些效应。不用任何函数展开,通过平衡态方程送代求解,得到精确的取向分布函数。从而计算各种物理量,给出了相变点序参数、熵变等量的精确数值。

关键词: 向列型液晶, 短程序, 格胞理论, 取向分布函数

Abstract: Some important physical effects appear due to short range order in nematic liquid crystals. On the basis of the cell theory, new numerical method is presented, which are used to calculate these effects.We do not use ann functional expansions but we obtain accurate orientational distribution functions by solving the equation of equilibrium state, using an iterative method. Then various physical quantities can be calculated. The accurate numerical results of order parameter at phase transition and entropy change etc. are given.

Key words: nematic liquid crystals, short range order, cell theory, orientational distribution function
