摘要：

Various ferroelastic and ferroelectric systems display several softening optic modes, all of which seem often to be related to the one observed transition. Furthermore, some of the soft modes have the symmetry of the order parameter, others even have a different one. It is shown that pseudosymmetric structures with some dynamic disorder are predestined to such behaviour. Details are exemplified by earlier and recent experimental results on ferroelastic and ferroelectric crystals.
