The ordering transitions of a two-dimensional lattice liquid characterized by a single favored local structure (FLS) are studied using Monte Carlo simulations. All eight distinct geometries for the FLS are considered and we find a variety of ordering transitions: first order, continuous, and multistep transitions. Using an entropy-energy representation of the freezing transition we resolve the dual influence of the local structure on the ordering transition, i.e., via the energy of the crystal and the entropy cost of structure in the liquid.
利用蒙特卡罗模拟研究了以单一有利局部结构（FLS）为特征的二维晶格液体的有序转变。考虑了FLS的所有八种不同几何结构，我们发现了多种有序转变：一阶转变、连续转变和多步转变。使用冻结转变的熵-能量表示，我们解析了局部结构对有序转变的双重影响，即通过晶体的能量和液体中结构的熵代价。
