A rigorous microscopic treatment of a nematic fluid system based on a pairwise interaction potential is immensely complex. For studying such systems molecular field theories are often the standard method of choice. In this paper we have chosen a simple effective potential U=u_{4}/v^{4}-u_{2}/v^{2}-Au_{2}/v^{2}〈P_{2}〉P_{2}(cosϑ) to study an isothermal-isobaric ensemble describing a liquid crystalline system. Using this we have studied in particular the pressure dependence of liquid crystalline phase transitions.
基于对向相互作用势的向列型流体体系的严格微观处理是极其复杂的。对于研究这类体系,分子场理论通常是首选的标准方法。在本文中,我们选择了一个简单的有效势 U=u_{4}/v^{4}-u_{2}/v^{2}-Au_{2}/v^{2}〈P_{2}〉P_{2}(cosϑ),来研究一个描述液晶体系的等温等压系综。利用这个有效势,我们特别研究了液晶相转变的压力依赖性。
