摘要：在前一篇文章中,我们用柔性连接点联系的刚棒模型代表半刚性链,建立了极小浓度方程。只有当体系浓度高于极小浓度时,才能得到稳定的各向异性相。本文根据前文的结果,分析了各种因素对液晶态稳定性的影响以及对各向同性—各向异性两相平衡的影响。
A general expression of the minmum concentration required for stableanisotropity was derived in preceding paper. The minimum concebtration is the func-tion of axtio and characteric stiffness of chain and temperature. In this paper, these fac-tors are discussed thoretically. Separation into an isotropic phase and somewhat moreconcentrated anisotropic phase arises as V_2>V_2~?. The concentration of both phase inequilibrium are influenced by the axis ratio and characteric stiffness of chain and tem-perature. The solvent and solute chemical potential for the order, or anisotropic solu-tion pass through a maximum and minimum, respectively.
