摘要 利用统计物理方法讨论了自由能 ,在此基础上 ,详细地推导了只考虑二阶和三阶维里系数近似下 ,刚性棒状分子的液晶统计理论。介绍了液晶的序参量 ,讨论了由序参量描述的液晶统计理论。简要地介绍了液晶的相变理论。最后从统计理论出发讨论了液晶的弹性系数与序参数的关系。 In this chapter, the basic method of the statistical theory and order parameters of liquid crystals are introduced. Based on them, Onsager′s statistical theory of liquid crystals, Maier Supupe′s mean field theory and second order phase transition are discussed. The elastic coefficients and the order parameters employed in continuous theory are introduced.
