基于非均匀流体集团展开的一种形式，对于讨论液晶的各种理论是有用的。利用一般形式，导出了确定三维液晶中跃迁序参量的方程。Lakatos关于在Onsager积分方程的近似下不存在相变的证明一般是不正确的。本文估计了二维棒状分子体系中的同位素相变和向列-近晶相变，后者的相变点与桤木和温赖特对二维硬球分子的估计一致。
A formalism based on cluster expansion for non-uniform fluid is found useful for the discussion of various thoeries of liquid crystals. Using the general formalism the equations which determine the order parameters for transtions in three-dimensional liquid crystals are derived. The proof by Lakatos that there is no phase transition within the approximation of the Onsager integral equation is found not to be correct in general. The isotopicnematic and nematic-smectic transitions in a two-dimensional system of rod-like molecules are estmated, the latter transition point agrees with what Alder and Wainwright estimate for a hard-sphere molecule in two-dimensions.
