本文从理论上研究了各向同性无序环境中近晶A到近晶C的相变。令人惊讶的是，我们发现，在干净的近晶-A到-C相变，近晶层的波动不影响过渡的性质，尽管事实上，他们是更强的存在下的障碍。结果表明，该跃迁的普适类是“随机场XY模型”（RFXY）的普适类。
We study theoretically the smectic-A to -C phase transition in isotropic disordered environments. Surprisingly, we find that, as in the clean smectic-A to -C phase transition, smectic layer fluctuations do not affect the nature of the transition, in spite of the fact that they are much stronger in the presence of the disorder. As a result, we find that the universality class of the transition is that of the "random field XY model" (RFXY).
