摘要实验证据表明，存在两种明显不同的近晶C到近晶A跃迁。第一类为二阶，两相均为零倾角；第二类为一阶，两相均为非零倾角。第二类转变的模型是近晶-A相中相邻层倾斜方向的“解耦”。
Abstract Experimental evidence is presented indicating that there are two distinctly different kinds of smectic C to smectic A transitions. The first type is second order with zero tilt in both phases, the second type is first order with a non-zero tilt angle in both phases. The model for the second type of transition is an “uncoupling” of the tilt directions of adjacent layers in the smectic -A phase.
