Layer compression modulus B measurements have been conducted near the transitions between smectic and hexatic phases with synclinic and anticlinic structures. In the synclinic structure, B shows no pretransitional softening near the phase transition. However, in the anticlinic structure, we observed evident critical softening of B near the smectic-hexatic phase transition. These results clearly reveal that the introduction of the in-plane hexatic order in the anticlinic structure is different from the usual smectic-hexatic phase transition.
已经在具有顺斜和反斜结构的近晶相和六方相之间的转变附近进行了层压缩模量B的测量。在顺斜结构中，B在相变附近没有预转变软化现象。然而，在反斜结构中，我们观察到在近晶-六方相转变附近B出现明显的临界软化。这些结果清楚地表明，反斜结构中面内六方有序的引入与通常的近晶-六方相转变不同。
