Abstract
It is shown that in some crystals the dislocations may play the leading part in phase transition anomalies of sound velocity and absorption as well as in strong q-dependence of the anomalous contribution to the elastic light scatering intensity. Theoretical results are compared with the experimental data available.Keywords
