本文推广了Suzuki处理经典系统和Ising模型的关联函数的严格公式,并应用在描述液晶相变具有转动不变性的Maier-Saupe哈密顿量上。结果表明,作者之一最近有关关联函数和磁双折射系数的微观处理,在所述近似范围内是正确的。文中并改进了Vertogen和Van der Meer有关液晶向列相的无规相近似的结果,提出了超越平均场近似描述液晶热力学性质的一个方案。The rigorous formula of Suzuki for correlation function of classical systems and Ising model is generalized and applied to the rotationally invariant Maier-Saupe Hamil-tonian of liquid crystals.The results show that the microscopic treatment of the correlation function and magnetic Cotton-Mouton coefficient by one of the authors is indeed correct within the approximation stated. The random phase approximation results of Vertogen and van der Meer is improved. A scheme to describe the thermodynamics of liquid crystals beyond the mean field approximation is proposed.
