摘要：

By the method of Landau thermodynamics a possibility of realization of phase transitions characterized by a vector of polarization and a tensor of deformation in crystals of all classes of point group of symmetry is investigated. The analysis is carried out by drawing up of the lists of invariants, constructed from a component of the order parameter. It is shown, that such phase transitions are possible in 14 crystallographic classes. The orientations of domain boundaries in low symmetrical phases and nonlinear effects are specified.
